I have tried to set up my 2x2 model this way, except replacing EV4 with
individual EVs for each subject ID. This gives me the following error:
Warning - design matrix uses different groups (for different variances),
but these do not contain "separable" EVs for the different groups (it is
necessary that, for each EV, only one of the groups has non-zero values).
I have set these individual EV's to be 1's for the same individual (ie,
1's in 2 rows for each EV), but 0's for all other rows. The design file
is attached.
Thanks for any assistance,
-Gabriel
