Dear Fs support,
If I have the following FSGD with 4 classes and 3 variables, and I'd like to run an interaction of ROIa x ROIb controlling for the third covariate (eTIV), would I use the following contrast?
[0 0 0 0 0.25 -0.25 -0.25 0.25 0.25 -0.25 -0.25 0.25 0 0 0 0]
For the interaction of ROIa x ROIb x class + eTIV.
Thank you so much in advance for your help!
All the best,
Fred
