Dear SPM users,
I have a little doubt about the use of covariates with multiple
In spm Batch Editor, in the SPM Statistics, in Factorial design module,
when you choice a multiple regression design you put your scans and
after there is a covariates label.
Further ahead, there is another label with Covariates. The unique
difference between the two options is that this last have and
I get the same result using the first covariates tag that the second
one, when the latter I put "interations none".
Although the result is the same, I would like to know what difference
there is between the two and what would be the correct way to do it.
Thank you very much in advance!!
