HI,
I may be missing something but can not figure out this
I have a higher level analyses -one sample t test with covariate-
performed on two copes from a first-level analyses. Each cope is
the output of a linear contrast that goes A: -1 0 1 and B: 1 0 -1
respectively. For A, the MEAN output of the higher level analyses
would give me a cluster that is identical to the one I get for B in the COVARIATE output
of the higher level analyses.
I understand in this test the MEAN output corresponds to stats where the effect of the COVARIATE is removed
but why does the output looks the same in both?
hopefully this is a rather trivial question!
Cheers
