hi,
I am trying something a little funky and need some stats help.
Using resting state data, for each subject, I have a conjunction of 3 seed to whole brain maps.
This gives me a binary volume with 1 or 0 to say if that voxel is common to all 3 maps. I want to compare those binary volumes across groups. I am wondering if a chi-squared test is valid, and how afni could do it.
tldr version: Can I do a chi-squared test, voxel wise?
thanks, Justin
