Hi,
new and hoping to get insight regarding a recurring 'invalid contrast' issue which seems to of cropped up previously.
After running a flexible_factorial design (2x3) and model estimation, I keep receiving 'invalid contrast' on the weighted vectors inside contrast manager.
I am dividing 1 by the number of subjects in each group so each subject has the same weight, totalling 1 (for each condition).
I have also attempted (1/3) to indicate group comparison but can not make any progress on the contrasts.
Any thoughts would be much appreciated.
