Dear Freesurfers,
I am trying to run a GLM analysis with 3 groups (1)long disease duration MS, 2)short disease duration MS, 3)healthy controls) and 1 variable (age).
According to the formula provided on freewiki:
N classes (N of variables + 1),
is this contrast matrix correct?
1 -1 0 0 0 0
1 0 -1 0 0 0
thank you,
Valeria
