Hi there,
if I do a multiple regression in which I put 2 groups but data are
coming from the same subjects, looking at one group gives 'wrong'
results as my nb of df is wrong .. I can of course have a look at my
stat tables but I was wondering if it's ok to modify the df in the
SPM.mat and then estimate the model ?? did someone try that ?
any input is welcome
cheers
Cyril
