Dear all,
I am setting up a new analysis and I am trying to figure out the design of my GLM.
The situation is as follows: I have 2 groups with 20 people in each group and where each subject has got 3 different scan sessions (fMRI).
So;
Group 1: 20 subjects with 3 scans for each subject (one week in between each scan)
Group 2: 20 subjects with 3 scans for each subject (one week in between each scan)
I assume this is a three level analysis with 40 subjects each having three sessions and where we are also interested in comparing both groups? So the Multi-session/Multi-subject repeated measures?
Basically, I am interested in the differences WITHIN each patient (over time), the group differences or the differences BETWEEN the patients of each separate group (mean group 1, mean group 2) and the differences BETWEEN both groups.
I hope my question is clear..
Can anyone help me please?
Best wishes,
Lies
