Hello,
If I were to run a DODS -- say, an F-test looking for group differences and interactions in thickness among drug users vs non- users, dependents vs abusers, and drug use in the last month vs no use in the last month -- how would I visualize the results? I assume there's no intelligible way to make an overlay out of interactions, unless you look at the F-test output one contrast at a time (e.g., what areas show a significant interaction in thickness between dependents vs abusers and use in the last month?).
Take care, Ian Carroll
Right, that would be a post hoc analysis. doug
