Hi FreeSurfers,
I have a more statistical question:
I have three groups of subjects and I want to examine the effect of a continuous variable (cognition). Is it possible to examine three groups? Or should I do pairwise comparisons? What would the contrast than look like? Something like this:
0 0 0 0 0 0 0.33 0.33 0.33
(first three zeros for the three groups; three zeros for age-correction; three weights for cognition scores)??
Thanks!
Heidi
