Anyone know what is the best way to do seasonality tests in SAS. Thanks
Seasonality is mostly tested for time series data. You should read about SAS-ETS - Overview of the Time Series Forecasting System
http://support.sas.com/documentation/cdl/en/etsug/63348/HTML/default/viewer.htm#tfintro_toc.htm
also look at proc SPECTRA for an alternate way of detecting seasonality.
SAS-ETS is a separate product from SAS-STAT.

I am using SAS/ETS, as the data I'm looking at is a time series..
Hello -
You might be interested in this SAS Global Forum paper: http://www.lexjansen.com/wuss/2004/posters/c_post_alternative_seasonali.pdf, featuring PROC X12.
In addition this example might be useful: http://support.sas.com/rnd/app/da/new/801ce/ets/chap5/sect21.htm
Thanks,
