Dear AFNI expert,
Hi,
My question is,
I finished the analysis with 3dMVM; however, I started to doubt whether using 3dMVM is correct in my case.
When I have a continuous between-subject variable of interest (not covariate of non-interest), can I use 3dMVM?
Specifically,
I have 2 categorical within-subject factors
2 continuous between-subject factors of interest
and 1 between-subject covariate of non-interest.
I want to examine 4 way, 3way, 2way, and main effect.
In this case (when I have continuous variable of interests), can I use 3dMVM? or... I need to use 3dLME?
I guess that 3dMVM (test of ANOVA, ANCOVA) would assume variables of interest as a categorical variable.
Thank you very much,
Irene
