Price 30 cents PREFACE The Consumer Price Index is one of the best known of the many sta tistic a l se rie s produced by the U.S. Government. B ecau se of its many u se s, such a s in wage escalation, deflation of the national pro duct and other important value se rie s, formation of fisc al and monetary p o licie s, and many other kinds of economic an alyses and ap p raisals, there is broad public interest in the methods employed in constructing the index and in the factors which affect its behavior. Since the index is a monthly se rie s, a su bject which has been widely d iscu sse d is the degree of season ality reflected in the index as a whole and in its components. This bulletin supplies b asic data with which Consumer Price Index se rie s can be adjusted for seaso n al variation. The bulletin was prepared by Marie Turnipseed in the Bureau’s Division of Consumer P rices and Price Indexes, under the general direction of Arnold Chase, A ssistan t Commissioner for Prices and Living Conditions. Apprecia tion is expressed for the advice and consultation of Abe Rothman and his sta ff of the Bureau’s Office of S tatistical Standards and the re search of Wylodean Treece of the Division of Price Operations.

Such seaso n al price movements may arise, for example, out of annually recurring changes in weather conditions, crop-growing cy cles, the common practice of having sp ecial s a le s during sp e cified months each year, holiday se a so n s, and r e g u l a r industry-model changeover periods. Although .movements of the sum mary, or all-item s, Consumer Price Index are affected only v e r y slightly by season al fa c to rs, the month-to-month changes in many of the component se rie s are determined to a significant extent by seaso n al influences. taneously. T h i s is especially true with respect to the Consumer Price Index, the all-item s index used for most practical pur p o se s. The administrative problems which might result from minor se aso n al fluctuations, when using the index (not adjusted for s e a sonality) for contract adjustments are mini mized, if s u c h contract adjustments are provided for on the b a sis of average price data for quarters or half years. Another consideration involves the problems which might result from publication of the Consumer Price Index on both a s e a sonally adjusted and a season ally unadjusted b a sis, esp ecially in months when the two indexes move in opposite directions. U sers of the index might find a season ally adjusted index, which gives different results from the unadjusted se rie s, confusing in practical applications. This problem would be com pounded by the fact that with a n y of the currently used methods for se aso n al adjust ment, every additional period of data intro Growing recognition of the importance of se aso n al influences in period-to-period sta tistic a l comparisons has, in recent years, directed attention to the season al compo nent in price trends. As a result, there have been requests for either season ally adjusted price indexes or for adjustment f a c t o r s which can be used to adjust or interpret in dexes p u b l i s h e d only on an unadjusted b a s i s .1 duced into the computation to b r i n g the se rie s up-to-date changes, to some degree, the se aso n al factors for the period immedi ately preceding. Although one of the primary goals of the B L S method of seaso n al adjust ment is the control, within acceptable lim its, of changes in se aso n al factors when a se rie s is updated, changes in the season al factors for recent years do occur each time an addi tional year’s data are included in the calcu lation s. The im plications of such changes in contract adjustments are obvious. While recognizing the usefulness of season ally adjusted data for many sta tistic a l se rie s, the Bureau of Labor S ta tistic s has,, for several reason s, not published the off!-* cial price indexes on a season ally adjusted b a sis. Seasonal fluctuations in the overall indexes are relatively minor, the result of offsetting seaso n al movements in their vari ous component se rie s taking place simul In its monthly an aly sis of the CPI, the BLS attempts to indicate in a general way— that is , without presenting s e a s o n a l l y adjusted indexes—the commodity and service a r e a s in which the price movements are ^See, for exam ple, Government Price S tatistics, Hearings before the Subcommittee on Economic Statist tics of the Joint Economic Committee, Congress of the United States (87th Cqftg., 1st se ss.), Pursuant to Sec. 5(a) of Public Law 304 (79th Congress), pt. 2, pp. 595-598. 1 analysis of current price trends. For some series, special expedients had to be adopted before the BLS season al factor computation technique could be applied, e.g.i for series in which price data were available for only selected months of each year. seasonal. Seasonal f a c t o r s have been available for this purpose over the years. In earlier years, they were computed by hand by standard textbook procedures; in more recent years, they have been computed with the use of the Census Univac m e t h o d s . Currently, these factors are computed on the b asis of the BLS techniques developed in connection with employment and unemploy ment sta tistic s. These seasonal factors are being made available now to meet, if only partially, the requests of economic analysts concerned with prices. A major revision of the Consumer Price Index will be introduced in December 1963, wh i c h probably will have a pronounced effect upon the season al patterns of many of these s e r i e s . The revision will include changes in city, item, and outlet samples and weights, in pricing procedures, and in the classification of items. Greater caution should be exercised in using these factors in the analysis of current price trends after that date. This bulletin includes a description of the BLS method used in computing the se a sonal factors currently in use; a discussion of its application to consumer price series; comments relating to specific series; and tables containing seasonal factors and the original price indexes for 66 s e l e c t e d se r ie s .2 Publication of seasonal factors is limited to selected series where the results, after intensive r e v i e w , seem reasonably satisfactory. The tables indicate which factors seem most appropriate for use in A seasonally adjusted series can be obtained by dividing the original price series for each month by the corresponding seasonal factor and multiplying by 100. For the histo rical series, generally covering June 1953 through May 1961, each month of each year has its corresponding factor. For indexes subsequent to the latest month given in the t a b l e , it is recommended that the set of factors identified in the same table as for "subsequent” years be used. 2A nalysts requiring additional tables generated in the course of the computer calculation of die season al factors presented in this bulletin may secure these from the U.S. Department of Labor, Bureau of Labor Sta tistics, Washington 25, D.C. THE BLS SEASONAL FACTOR METHOD activities in this area have r e s u l t e d in changes and improvements in the method and its electronic computer application.4 This description of the method is an adaptation from t h e s e earlier articles. (Additional changes have been giade in the method in General Method The BLS method for deriving seasonal factors for economic time series was devel oped late in 1959. It was introduced early in i960 in application to the l a b o r force se r ie s .5 Since then, the Bureau's continued 5For a detailed description of the method and pro cedure at that time, see Special Labor Force Reports, No. 8, New Seasonal Adjustment Factors for Labor Force Components, by Morton S. Raff and Robert L. Stein, U.S. Department of Labor, Bureau of Labor Sta tis tic s, Reprint 2349 from the Monthly Labor Review, August I960. A full description of the method and its computer application which w as used in deriving the season al factors for the price se ries is given in "The BL S Sea sonal Factor Method," a paper presented at the Inter state Conference on Labor S ta tistics, Atlantic City, N .J., Jun e 21, 1962, by Abe Rothman, Office of Statis tical Standards, Bureau of Labor S ta tistics. 2 If the estimated trend-cycle is a good fit, then the irregular component will have a random appearance. If, on the other hand, there are places where the trend-cycle does not fit well, as when a moving average fails to penetrate the peaks and troughs in the original series, then the irregular component will include a residual trend-cycle in ad dition to erratic fluctuations. application to the labor force series in 1963* These modifications, however, were not used in this study.) The BLS procedure is based on the ratio-to-moving-average method. It divides the original time series (O ) into three com ponents: The trend-cycle (T), or the smooth curve which shows the underlying movement of the series; the seasonal (S ), or the part which is related to the particular month of the year and which has approximately the same pattern from one year to the next; and the irregular (I), or the random fluctuations remaining after the fitting of the trend-cycle and seasonal. A multiplicative relationship is assumed (O = TSI). Before the second iteration begins, an improved estimate of trend-cycle is obtained. This is calculated by combining the trendcycle used in the first iteration, i.e ., the 12-month moving average, with any trendcycle that can be withdrawn from the irregu lar ratios developed in the first iteration. A serious defect of the 12-month moving aver age is that it does not follow the original series very well when there are rapid changes in level or direction. Any error in the trendcycle produces a corresponding error in one or both of the other two components, chiefly in the irregulars, since the season als have been obtained by averaging the SI ratios for su ccessive years. A w e i g h t e d 7-month moving average of the series of irregulars is computed to remove the residual trendcycle. The 12-month moving average of the original data from the first iteration is then multiplied by this smoothed irregular to ob tain the improved estimate of trend-cycle, with which to start the second iteration. The computations performed in devel oping the season al factors are a series of successive approximations, in which each iteration, or cycle of computing steps, gets closer to the desired final result. Iterations are performed in se ts of three, each iteration beginning with an estimate of the trend-cycle (T) and each resulting in an improved e sti mate for each of the components. The first such estimate is the c e n t e r e d 12-month moving average of the original data. This estimate for each month is then divided into the corresponding original value (O ) to pro duce a series of seasonal-irregular ratios (SI) (O 5 T = S I ) . With each month treated separately and with years arranged consec utively, 5-year weighted moving averages of these ratios are computed to provide e sti mates of the unforced seasonal factors (S')« The unforced seasonal factors for each year are then adjusted to give a monthly average of 100 for the year. These forced seasonal factors (S) are the final season als for the cycle. Each final seasonal is divided into the corresponding seasonal-irregular to obtain the irregular (SI ? S = I). This completes the first iteration. A second and a third iteration repeat the steps of the first iteration. Investiga tion has shown that three iterations for each set is the optimum number. Too few itera tions leave some of the trend-cycle in the irregular component, while too many itera tions build up erratic fluctuations in the trend-cycle. The seasonal factors are not appreciably affected by moderate departures from the optimum number of iterations. * - The procedure also includes a routine for handling extreme values that do not seem 3 to belong to the general pattern of the data. (These values may have a real economic cause such as very unseasonable weather or a strike.) The test identifies extreme values, if any, and provides replacement estim ates. It follows the same general, pattern of com putational steps as each of the iterations. The test procedure, however, uses special weighting patterns which give zero weight to the*central value in computing the criterion against which each “ te st* irregular is judged in order to minimize the effect of an extreme value on the trend-cycle and seasonal com ponents. The distribution of the "te st” ir regulars is then examined to see whether any of them lie outside specified control limits. determined that the standard deviation of each seasonal factor (erg) may be approximated as 0.6 of the standard deviation of the irregulars. This dg may be used to test each season al factor for significance as compared to no seasonality (or 100). To test the signifi cance of the season al movement from one month to another, the formula for the differ ence in season al f a c t o r s is su ggested .5 Differences and percent c h a n g e s in the factors generally are of about the same mag nitude. The correlation between the se a sonal factors is small and may be disregarded. If the te std isc lo se s no extreme values, the trend-cycle, season al, and irregular com ponents of the third iteration are regarded as final. The BLS method of computing season al factors differs in several respects from ear lier methods. Changing seasonal factors provide insight into underlying economic and technological forces which escape detection in fixed season als. A number of price series, for example, show a narrowing of season al movement in response to attempts to elimi nate production and marketing peaks and valleys. Advantages and Limitations of the B LS Method If extreme values do exist, each is re placed by a substitute value which is the product of the trend-cycle and seasonal com ponents from the test iteration. This modi fied original series is then processed in the usual way, starting with the centered 12month moving average and repeating the first three iterations. The trend-cycle and se a sonal components from this third iteration are final. The original extreme values are then restored, to compute the final irregular com ponent and the seasonally adjusted series. This assign s the deviation in an extreme original value to the irregular component. The BLS method also provides that, when a s e r i e s is updated, the seasonal factors relating to the earlier years of a series will remain practically the same a s those of prior series. Magnitude of changes for the more recent period are also reduced. The season al pattern for the current year, however, will never be exactly like the average for any se t of past years. Marketing activity, for example, may vary from year to year with weather conditions. Although new automobile models are introduced each year, Standard deviations of the irregulars (dj) are calculated both before and after ex treme values are replaced. These are useful in evaluating the effect of the test iteration and the replacement of original observations identified as extreme, and as g u i d e s in measuring the reliability of the seasonal factors.

Charts 1 and 2 show the original price index and its three final components: Trend-cycle, season al factors, and the random or irregular component, over the period from June 1953 through May 1961. The timing dates of the extreme values in the original series are identified on the chart of irregulars, the com ponent to which the deviations have been assigned. Chart 3 shows the changes over the years in each of the 12 monthly seasonal factors. Chart 4 shows for selected months, March, June, and December, the relationships of the final seasonal-irregular values to the final season al factors. In addition, the interpretation of se a sonal factors is complicated by the problems of measurement inherent in the original data. To the extent that original series are subject to sampling or reporting error; the seasonal factors will be subject to uncertainty.

The price series for (Cont’ d on page 6 thru 8) SELECTION OF SERIES AND COMPUTATION PERIODS to average factors under these circumstances, and lack of basic data or budgetary consid erations limited the recalculation of such price series for the earlier part of the period. About 90 series were chosen initially for the computation of seasonal factors, and 66 of these were selected for publication. The major criteria for selection were the importance of the series, the existence of a strong season al movement, special interest in the season al pattern, and the absence of procedural p r o b l e m s . The 8 major-group series, for example, were selected because of their importance in the Consumer Price Index. As examples of procedural problems, some series which might otherwise have been selected were omitted because they were not long enough for the BLS method to be appli cable, i.e ., 6 years, or because there was a change in the procedure for calculating the price series during^the 6-year period, which would have a pronounced effect upon the se a sonal variation. It would not be appropriate The season al factors generally cover the 8-year period, June 1953 through May 196l, computed from price series extending an additional 6 months at each end, thus covering from December 1952 through Novem ber 1961. The series were not extended back of December 1952 because changes in city, item, and outlet sample, and in pricing pro cedures which were introduced in the 1953 revision of the Consumer Price Index, had pronounced effects upon seasonal patterns. Shorter periods of time were selected for some series because of procedural changes introduced after June 1953* (Cont'd on page 9) 5 Chart 1.

This kind of evaluation was an important consideration in determining which of the other series should be published.

The factors as given in the tables are recommended for adjusting the historical index series shown with them* that is, for the period shown, usually June 1953 through May 1961. Each month of each year has its corresponding factor. Those for the most recent year, generally June I960 through May 1961, are suggested for adjustment of data subsequent to May 1% \. These are shown on the last line of each seasonal fac tor table. Since the original factors for June I960 through May 1961 relate to parts of 2 calendar years and may not average 100.0, the unforced factors from computer calcula tions were tested and adjusted, if necessary, ^In the computer procedure, forcing of factors is on a calendar year b a sis. When a series does not start with a January value or end with a December value, the forcing is performed in two sta g e s. The first (or last) 12 . consecutive unforced se aso n als are used to calculate a forcing factor. This factor is applied to the unforced se a so n a ls for the partial year. For each of the remaining years, the forcing factor is based on the calendar year. This procedure is used for the B L S employment se ries. Any method of forcing, however, creates breaks in a se rie s; and this problem is under consideration by the Bureau. COMMENTS ON SPECIFIC SERIES All Items and Major Groups seasonal m o v e m e n t between su ccessive months is significant only twice (2d ^ )J For the earlier part of the computation period, about half of the factors are significantly different from 100.0, and the seasonal move ment between su ccessive months is signifi cant about one-third of the time. Among the major groups, the apparel, food, and trans portation series clearly show significant seasonal movement. For apparel, for exam ple, the range of the "subsequent” factors is from 99.4 to 100.9, with all 12 differing significantly from 100.0 and with seasonal movement between successive months signi ficant in 6 c a se s. The all-items series and the 8 major groups were selected for computation and publication b e c a u s e of their importance. Except for food, apparel, and transportation, however, these series are characterized by very little seasonal variation and a relatively high degree of irregularity. In the all-items index, for example, the patterns of seasonal variation, the timing of the peaks and troughs, vary so greatly and in such a way among the component series that the movements offset each other to a very large extent. The reliability of the seasonal factors should be considered when using them. For the all-items index, for example, the range of the "subsequent” (i.e., current) factors is from 99.8 to 100.2. Only two of these factors differ significantly from 100.0, i.e., by as much as two standard deviations (2crs)» The The apparel series in the tables covers only the period June 1959 through May 1961, because of a change in statistical procedures .7 Z<fd = 2.8284 crs 10 footwear, and public transportation. In the series for rent and household operation, the range of factors for the most recent year of the computation period is only 0.2; for food away from home and footwear, 0.3; and for public transportation, 0.6. For public trans portation, the series of factors as a whole is erratic and irregular, with a value of 0.3 for 2cg. The other 8 subgroups are shown in the tables: Food at home, gas and elec tricity, solid and petroleum fuels, housefurnishings, men’ s and boys’ apparel, women’ s and girls’ apparel, other apparel (excluding footwear), and private transportation. for seasonal items of apparel, introduced in June 1959. In the computation of seasonal factors, a recalculated but unpublished price index, which incorporated the revised pro cedure, was used for the period from June 1959 back to December 1952. The evaluation above, however, is based on the standard deviation calculated for the entire period. Effective in March 1963, a revised pro cedure for e s t i m a t i n g the price level in unpriced cities of all items of apparel was introduced, which affects their seasonal pat terns. Instead of using as an estimator the price movement of the 5 large cities which are priced monthly, the price level of the unpriced cities is now held constant. The indexes move somewhat differently, and the "subsequent” seasonal factors are not strictly applicable after February 1963? The effect of this change in procedure upon the season al pattern of the all-items series is negligible, since this estimated part of apparel has rel atively little i m p o r t a n c e in the all-items series. The men’s and boys’ and women’s and girls’ apparel series in the tables cover only the period June 1959 through May 1961, for the same reason that the entire period for the total apparel series is not included in the table. The revised procedure for calculating the price indexes for all-items of apparel, which is discussed in the comments on the all-items and major-group series, applies also to the housefumishings9subgroup. The effect of the change in procedure in this sub group upon the seasonal patterns of the hous ing series and the all-items series is negli gible. In the personal care series, this same change in procedure wias made for several of the commodities. The relative importance of these commodities is large enough for the revised propedure to have a slight effect upon the season al pattern of the personal care se rie s.8 Groups, Subgroups, and C la sse s of Items of Food at Home Subgroups Thirteen of the 17 series in this highly seasonal category were selected for compu tation (including poultry and lamb as c la sse s of items even though there is only one priced series in each). The factors for beverages and fats and oils are not published because of the irregular and e r r a t i c nature of the series. Computations of seasonal factors for all 13 subgroups were made for evaluation. After review of the results, it was decided that 5 series should not be published: Food away from home, rent, household operation, 8 This revised procedure w as introduced while this bulletin was in preparation. Indexes for the period prior to March 1963 are being recalculated for these se ries, according to the revised procedure. Seasonal factors, based upon the recalculated price series, may be secured upon request from the U.S. Department of Labor, Bureau of Labor S ta tistic s, Washington 25, D.C. ^See footnote 8 11 example, for the peach series, an arithmetic average of the three indexes for July, August, and September of 1953 was calculated and associated in point of time with August. The same thing was done for 1954. A straightline interpolation was made between the two values. The r e s u l t i n g indexes for the unpriced months, October 1953 through June 1954, were used as estimates for those months. After the machine computations had been made, the unforced seasonal factors for the pricing season of each calendar year were forced to average 100.0. Standard devia tions (0.6o|) were then calculated for this set of factors. Items of Food at Home Twenty-eight items of food at home were selected for computation: All the highly seasonal fresh fruits and vegetables except com-on-cob and grapefruit, samples of those meats and dairy products which show pro nounced s e a s o n a l patterns, eggs, cola drinks, hydrogenated shortening, and lard. Corn-on-cob and grapefruit were excluded^ because of a procedural problem. Com-on-cob has been priced only since the summer of 1961 and grapefruit has been priced yearround only since 1959. Four series were not considered s a t i s f a c t o r y for publication because of the irregular and erratic nature of their season al movement: Lettuce celery, cola drinks, and lard. The factors for these four seasonal fruits were calculated more recently than for the other series (as part of a special study), so were developed from price indexes extend ing through the pricing season s of 1962. In several of these series, there are months when price indexes have not been published because an adequate number of price quotations had not been collected. For each of these months, the index was e sti mated by applying the weighted a v e r a g e month-to-month price relative of all cities from which an adequate number of price quo tations had been collected for each of the comparable months, to the index of the earlier month. “Other” Housing Series Six series below the subgroup level in the housing group were selected for computa tion: Residential heating gas, gas for other than residential heating, electricity, solid fuels, fuel oil #2, and laundry soap and deter gents. The factors for two series, electricity and l a u n d r y soap and detergents, are not being published. The range of factors for the most recent year of the computation period for the electricity series is only 0.3. The series for laundry soap and detergents shows more seasonal variation (with a range of 0.7 for the factors for the most recent year), but the season al movement is very irregular and erratic. The four fresh fruits which are priced only for specified season s, peaches, straw berries, grapes (seed less), and watermelons, presented special problems, both methodo logical and operational. Hypothetical price indexes must be provided for all intervening months between pricing season s to preserve the proper trend-cycle for the price series. In other words, the indexes fof .the priced periods must be associated with their appro priate periods over time. Estimates of trendcycle were used as price indexes. These estimates were made by making a straightline i n t e r p o l a t i o n between the average indexes of su ccessive pricing season s. For The solid fuels s e r i e s in the table covers only the period June 1956 through May 1961. Only since December 1955 has the price series been calculated monthly. 12 taken to isolate the two types of price changes to prevent the seasonally adjusted price series from smoothing the annual price change over the year rather than appearing in the month in which list prices are changed. This point becomes especially important if the direction of annual price change should be reversed.”10This means that in times of rising prices, the yearend rise may all be credited to seasonality whereas part is the year’ s accumulated rise resulting from the rising trend. When the cycle turns down, the se a sonal adjustment factors, influenced by data for previous years, overstate the seasonal swing. “Other” Transportation Series New automobiles is the only additional series in the transportation group, for which seasonal factors are published. The factors for this series were calculated more recently than those for most of the other series (as part of a special study), so were developed from data extending through 1962. The series of published factors does not start until Jan uary I960 because of a change in index pro cedure in 1958. A revised method for intro ducing new models became effective in the fall of 1958. Instead of taking the change to a new model in 1 month, the current procedure is to use the relative importances of sa le s of the new and old models as weights, until 90 percent of the sa le s are of the new model. In order to obtain a 6-year price series which would more nearly reflect the current CPI procedure, estimated price indexes for Octo ber, November, and December of 1957 were substituted for the indexes which have been published. The difference in the index levels between September 1957 and January 1958 was distributed by the relative importances of the month-to-month percent changes in the indexes from September 1958 to January 1959. The factors from I960 to date are practically free from the effect of these estimated price indexes. Standard deviations were calculated for the period of the published factors. Interest has been expressed in two other transportation series which have considerable seasonal variation: Used automobiles and gasoline. The used automobile series is excluded for technical reasons. In the CPI procedure, an intra-annual adjustment is made to reported prices, designed to maintain an automobile of "constant age” . In other words, the price level reflected in the index every month is an estimate of the price level of an automobile of the same age, for example, exactly 4 years. January is regarded as the birthmonth, and the prices for subsequent months are adjusted until the following Jan uary. At that time, an annual comparison is made with the price of the model 1 year ear lier. For example, for a 4-year old automo bile, the price of a 1959 model in January 1963* is compared with the price of a 1958 model in January 1962. This adjustment of prices within the year may be regarded as a variant of seasonal adjustment. In regard to gasoline, the problem relates to the length of the price series as currently computed and the amount of irregularity in the seasonal variation. It was computed monthly for only 5 years of the computation period for season al Care should be taken in using the fac tors for this series. As stated by the Price Statistics Review Committee formed under a contract which was entered in to by the Bureau of the Budget and the National Bureau of Economic Research in July 1959, “ For certain commodities price changes are customarily made annually at the date of model change. In addition there may be a seasonal pattern superimposed that reflects varying discounts from list prices. When price movements have been predominately in one direction (recently upward) over a period of years, care must be ^Government Price Statistics, op. cit., Pt. 1, Jan uary 24, 1961, footnote 7, p. 45. 13 factors; and d ur i ng ' the first year of that period, the n u m b e r of priced cities was increased from 19 to 46. 6 years was selected because of a signifi cant changeincity sample in December 1956. The small cities of the D stratum were added to the series at that time, bringing the total sample up from 14 to 19. The computation period, February 1956 through January 1962, still o v e r l a p s by about a year the series based on only the 14 larger cities. The pub lished series, however, cover only the period from June 1957, 6 months after the change in city sample. After machine computation, the final unforced season als for each four suc cessive quarterly periods were forced so as to average 100.0, with the grouping starting at the end of the series. In other words, September and December of 1 calendar year were grouped with March and June of the fol lowing year. The regular computer procedure was applied^to the partial year at the begin ning of each series. Also, standard devia tions were recalculated from the quarterly irregulars for the published period. Special Groups Seasonal factors were computed for 8 special-group series for evaluation. Three series (commodities, durables le ss cars, and services le s s rent) are not being published because of lack of significant seasonal move ment. The other five are presented in the tables. Except for all items le ss food, these series are limited to the period June 1956 through May 1961. Only since December 1955 have the price series been calculated monthly. Quarterly Series Nine quarterly series were selected for computation: T e x t i l e housefumishings, sheets, appliances, television se ts, floor coverings, furniture and bedding, men’ s yearround suits, tires, and p r e s c r i p t i o n s and drugs. These presented several problems. Figures for missing months in price series were estimated by repeating the quarterly index for the months immediately before and after.11 The minimum computation period of Except for sheets, . television se ts, men’ s year-round suits, and tires, the series are characterized by little or no seasonal variation and a relatively high degree of irreg ularity. Only these four are included in the tables. The factors for tires have a rela tively large standard deviation, but much of the irregularity occurred in 1959 or earlier. 11 An alternative method of estimating m issing months, straight-line interpolation, was used in a preliminary test made with several se rie s. The two methods gave practically identical factors for the quarterly months (with only a few variations of not more than 0.1). 14 Seasonal Factors for Selected Consumer Price Index Series Year Ja n .
