Hi everyone,
I am trying to analyze the effect of 2 covariates (both continuous variables) on 4 different emotion conditions in spm8. I have tried setting this up in the 2nd level analysis, as full factorial, using one factor with 4 levels, then specifying my 2 covariates of interest. I had to repeat each covariate 4 times to match each emotion condition within the same subject.
Is this the correct way to essentially set up an Ancova in spm, or does anyone have a better suggestion?
Thanks!
Ryan
