Dear SPM-community,
A simple question this time:
I want to perform a group-analysis (2nd level) with a covariate
(behavioral performance). So my matrix with two collumns looks
like this:
covariate task
What should be the contrast if I want to test task (while taking into
account the covariate)??
1 0
0 1
1 1
Thanks in advance,
Matthijs
