Dear SPMers,
I have set up a flexible factorial design with the factors subject, group (1
vs 2), and condition (1 vs 2). I modelled the main effects of group,
condition, and group x condition with a design matrix excactly like in the
Gläscher & Gitelman Tutorial Design 3, p.10. I found a nice interaction of
group x condition, which I wanted to explore with post-hoc comparisons, e.g.
(group1, condition1) > (group2, condition1). However, I can't find the proper
contrast weight for this comparison. Has anybody a solution for this?
Many thanks in anticipation,
Udo
