Hi group,
I've posted this problem a while ago without getting an answer, and I
still didn't find out myself,
so here is another try:
(I'm working with SPSS 9.0)
When I do a GLM-repeated measures analysis, in SPSSI get tests for all
interactions bewteen every within-and every between-subject factor.
Supposed I don't want to include all these interactions in my model,
e.g. the interaction between a covariate and a within-subject
factor: Is there a way to adjust my model not to include this effect?
(Syntax welcome!)
Or, if this is not possible (I vaguely remember MANOVA in former
versions did not test these interactions as default), is there a good
statistical reason to test all possible within*between-interactions?
Any help is appreciated,
Johannes Hartig
