Dear List,
we have data from two experiments using the same stimulation, one in PET
and one in fMRI. We did a random effects analysis of both studies and
would now like to compare the results statistically.
We are interested in what is common in both modalities and, of course,
in the differences.
Can we use the method described in
http://www.mailbase.ac.uk/lists/spm/2000-11/0005.html
with using the PET data as Group1 and the fMRI data as Group2 ?
What about global scaling when comparing data from different modalities ?
Do we have to apply scaling in the second-level ?
Thank you for your time,
Thomas Stephan
