The TIMESERIES Procedure

SEASON Statement

SEASON statistics < / options > ;

A SEASON statement can be used with the TIMESERIES procedure to specify options that are related to seasonal analysis of the time-stamped transactional data. Only one SEASON statement is allowed. The options specified affect all variables specified in the VAR statements. Seasonal analysis can be performed only when the length of the seasonal cycle specified by the PROC TIMESERIES statement SEASONALITY= option or implied by the ID statement INTERVAL= option is greater than one.

The following seasonal statistics are available:

NOBS: number of observations
N: number of nonmissing observations
NMISS: number of missing observations
MINIMUM: minimum value
MAXIMUM: maximum value
RANGE: range value
SUM: summation value
MEAN: mean value
STDDEV: standard deviation
CSS: corrected sum of squares
USS: uncorrected sum of squares
MEDIAN: median value

If none of the season statistics are specified, the default is as follows:

   season n min max mean std;

The following option can be specified in the SEASON statement following the slash (/):

TRANSPOSE= NO | YES: specifies which values are recorded as column names in the OUTSEASON= data set. TRANSPOSE=YES specifies that the seasonal indices be recorded as the column names instead of the statistics. The TRANSPOSE=NO option is useful for graphing the seasonal analysis results with SAS/GRAPH procedures. The TRANSPOSE=YES option is useful for analyzing the seasonal analysis results with SAS procedures or SAS Enterprise Miner software. The default is TRANSPOSE=NO.
