Hello FSLers
I wonder if someone could doublecheck my higher level design setup (esp. the
orthogonalisations)
I have two groups and one behavioral measure
Design looks like this:
Group EV1 EV2 EV3 EV4
1 1 0 6.5 0
1 1 0 0.6 0
1 1 0 3.4 0
1 1 0 9.0 0
1 1 0 13.8 0
1 1 0 14.1 0
1 1 0 7.2 0
1 1 0 6.2 0
1 1 0 6.5 0
1 1 0 7.1 0
1 1 0 7.4 0
1 1 0 7.3 0
2 0 1 0 9.0
2 0 1 0 8.1
2 0 1 0 6.0
2 0 1 0 2.1
2 0 1 0 1.6
2 0 1 0 -3.3
2 0 1 0 13.2
2 0 1 0 2.9
2 0 1 0 22.9
and orthogonalisations EV3 wrt EV1 and EV4 wrt EV2
If I have a contrast
Behav(GroupA) > Behav(GroupB): EV3 = 1, EV4 = -1
can I confidently conclude from the results that these are areas where group
A shows a stronger positive correlation between BOLD signal (for the cope of
interest) and the behavioral measure than group B ?
Thank you very much !
Anna
