Dear AFNI users,
I ran 3dRegAna using one covariate. How should I get the value of overall R-square for the model I have used? I have created the bucket dataset using -bucket option and I see there is a sub-brick that contains R-Square. Is this R-Square for the whole model OR for a particular voxel where I have chose to click in AFNI overlay-underlay? I am interested in knowing how much total variance is explaned by the model overall.
Your helps is greatly appreciated.
Sincerely,
Shant
