Hello,
Is it possible to interpret negative z-score values in PPI interaction term?
Let’s say I have task condition A, seed, and seedXconditionA as my EVs, and I have contrast [0 0 1] to look at significant connectivity increase in condition A relative to baseline. In my higher level group analysis, group mean result contains positive as well as negative z-values. Can I say that strongly negative regions decrease connectivity with the seed region in condition A relative to baseline?
Thank you!
