Hi all,
I would like to correct for drop-outs during my longitudinal fMRI study. With drop-out I mean not the signal drop-out (incomplete brain coverage), but the participants who not take part in either the first or the second time point of the study.
I know multi level models for SPSS, but for SPM12 I am not currently aware of any models which can correct for these drop-outs.
Thank you in advance for replying / trying to find a solution for my issue,
Meltem
