Hi, yes, say you have 3 subjects and one factor with 2 levels
at the highest level analyses you may specify the betas in different orders
subj1 beta1 subj1beta2
subj2 beta1 subj2beta2
subj3 beta1 subj3beta2
or
subj3 beta1 subj3beta2
subj2 beta1 subj2beta2
subj1 beta1 subj1beta2
or any other combination
you might see a similar set of clusters in both cases but order influences the stats in a funny way
guess there may be implications to assess significance when the effects are borderline
but in any case it is weird and am curious to learn what is the reason of this behaviour in the first place
rgds.
