I'm trying to setup an analysis looking at 4 groups (control, patient group A, patient grp B and patient group AB which has both A and B comorbid) using the 2x2 ANOVA directions given in FEAT. What would be the best way to set up the GLM? EV1= control EV2=patients A EV3=patients B and EV4=patients AB with everyone 1 in the group column and 1's in the EV for each group? Then for contrasts has 3 contrasts (A, B and AB) and 3 F-tests?
Thanks for all your help,
Jen
