The X11 Procedure |

The output data set produced by the OUTSTB= option of the PROC X11 statement contains the information in the analysis of variance on table D8 (Final Unmodified S-I Ratios). This analysis of variance, following table D8 in the printed output, tests for stable seasonality (refer to U.S. Bureau of the Census, 1967, Appendix A). The variables in this data are:

- VARNAME, a character variable containing the name of each variable in the VAR list.
- TABLE, a character variable specifying the table from which the analysis of variance is performed. When ARIMA processing is requested, and two passes of X11 are required (when TDREGR=PRINT, TEST, or ADJUST), Table D8 and the stable seasonality test are computed twice; once in the initial pass, then again in the final pass. Both of these computations are put in the OUTSTB data set and are identified by D18.1 or D18.2 respectively.
- SOURCE, a character variable corresponding to the "source" column in the Analysis of Variance table following Table D8.
- SS, a numeric variable containing the sum of squares associated with the corresponding source term.
- DF, a numeric variable containing the degrees of freedom associated with the corresponding source term.
- MS, a numeric variable containing the mean square associated with the corresponding source term. MS is missing for the source term "Total."
- F, a numeric variable containing the F statistic for the "Between" source term. F will be missing for all other source terms.
- PROBF, a numeric variable containing the significance level for the F statistic. PROBF is missing for the source term "Total" and "Error."
