Dear Donald
Thanks so much!
So I have 2 groups. (group 1 and group 2)
covariate: Name=age. Interactions=with factor 1
The design graph is: group 1, group 2, age@sF21, age@sF22
And the contrasts I used are: 0 0 1 -1 and 0 0 -1 1
Hope that's correct?
But 'age@sF21, age@sF22' seem quite strange?
Thanks!
