Dear Expert
So I would like to know the mean activation among 2 groups (with different variances within groups).
Also, I will have age as a covariate.
My guess is this:
* The first 2 inputs are from group A and the last 2 inputs are from group B
* EV1,EV2 are groups whereas EV3,EV4 are ages.
Group EV1 EV2 EV3 EV4
1 1 0 23 0
1 1 0 22 0
2 0 1 0 30
2 0 1 0 23
Contrast1 0.5 0.5 0 0 (mean activation)
Contrast2 -0.5 -0.5 0 0 (mean deactivation)
Hope that's ok.
Thanks so much!
