Hi,
Thanks for your instant reply!
What’s the difference between demeaning within group and across all subjects? There were situations that demean within group in elsewhere while test the same model as mine, egg. https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ind1005&L=FSL&P=R18717&1=FSL&9=A&I=-3&J=on&X=3A86614E58392038A4&Y=qinxu.china%40gmail.com&d=No+Match%3BMatch%3BMatches&z=4
I didn't express my second question clearly. Yeah, I want to test the overall linear relationship between FA and behavior. But i want to make sure if i could add an EV with 1s besides the EV of behavior scores? The contrast was [0,1] if I add an additional EV considering the groups ?
Thanks.
Best,
Qin
