Hi,
Thank you for the reply, I am just not sure if it is correct.
I used the glm gui and created the following for design.mat and design.con
Number of main EVs= 4
Number of add.voxel-dep. EVs=0
Group EV1 EV2 EV3 EV4(demean_age)
1 1 0 0 14
1 1 0 0 -2
1 1 0 0 9
2 0 1 0 -5
2 0 1 0 -3
2 0 1 0 5
3 0 0 1 8
3 0 0 1 3
3 0 0 1 -10
Contrast=3, F-test=3,
EV1 EV2 EV3 EV4 F1 F2 F3
C1 X A-B 1 -1 0 0 X
C2 X A-C 1 0 -1 0 X
C3 X B-C 0 -1 1 0 X
Does the contrast c1 to c3 already regress out the effect of age if I set up in this way?
Sorry for the simple question,
Thank you in advance
Natalia.
