Hi:
My experiment has 2 fixed factors(a,b), and each of these factors have
two levels. In AFNI I used adANOVA3 type 4 in which subject was a radom
factor(c). I made the contrast of a1 and a2 at two levels of b: (a1-a2)_b1,
(a1-a2)_b2. How can I make a contrast of (a1-a2)_b1 and (a1-a2)_b2, that
is [(a1-a2)_b1]-[(a1-a2)_b2].
Thank you all.
best wishes!
