Dear SPM-experts,
I am currently facing a problem which has been posted to the list but I
can not find a solution:
https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ind0808&L=SPM&P=R7442&I=-3&d=No+Match%3BMatch%3BMatches
I would like to enter age as a covariate of no interest in a repeated
measures ANOVA design (20 subjects, 1 condition with 3 levels). The
question is how to construct the covariate vector? Since the scans are
carried out within a rather short duration, age does not change between
the scans. However, entering the same age for each of the 3 scans for
each subject gives the identical result as without the covariate.
Thank you for your help in advance,
Andreas.
