Hi FSL Group,
Reading up on previous covariate inclusion in models I had thought the
following model was doable but I am getting an error.
I have three groups and three covariates I want to include (not super
interested in seeing the effect of group so I thought I could enter it
like this). Thus I coded it like this:
Group1 Group2 Group3 AgeCovariate GenderCovariate
ScannerVersionCovariate
1 1 0 0 34
1 1
1 1 0 0 45
2 2
1 1 0 0 52
1 2
2 0 1 0 34
2 2
2 0 1 0 76
2 2
2 0 1 0 24
2 1
3 0 0 1 19
2 1
3 0 0 1 9
1 1
3 0 0 1 35
1 1
Do I need to split the each covariate into 3 columns one per group?
Thanks,
Vina
