Dina,
The TEST subcommand offered in MIXED should be capable of estimating
the simple effects you desire. First thing's first, though...You must
properly parameterize the model. I believe I recently posted a
solution for parameterizing a similar model here:
http://www.listserv.uga.edu/cgi-bin/wa?A2=ind1104&L=spssx-l&P=R23020If you are interested in fitting this model via the MIXED procedure
and would like some assistance after reading up on linear MIXED models
(including the post above), write back and I will try to help.
Best wishes,
Ryan
