Hello SPM
I am running a multiple regression in SPM8, using 2 groups and 1 score,
where I would like to find where controls show more positive correlation
with the score than do patients during a task.
I have chosen
Under Design
>multipleRegression
Scans: 8 control and 8 patient con.img files~task>baseline
Under Covariates
>3 covariates:
group, scoreControls, scorePatients
vector for group:
1 1 1 1 1 1 1 1 -1 -1 -1 -1 -1 -1 -1 -1
vector for scoreControls:
x x x x x x x x 0 0 0 0 0 0 0 0
vector for scorePatients:
0 0 0 0 0 0 0 0 x x x x x x x x
x=number value
correlation of score is greater in controls than patients during task:
[0 1 -1]
correlation of score is greater in patients than controls during task:
[0 -1 1]
activation during task , controls > patients [1 0 0]
activation during task, patients >controls [-1 0 0]
Please correct where needed.
Thanks for your time and attention,
Maria
