Hi Freesurfer
experts,
I want to do a group
ANOVA analysis with one co-variable. I have read the corresponding wiki but
still have some problems. I need your help.
I have 4 group
subjects (A1B1, A1B2, A2B1, A2B2) and one co-vaiable (C).
I want to get the
interaction between A and B. However, because C is different in different
groups, I need to rule out the influence from C in my ANOVA
analysis.
So the model is
A*B+C.
The fsgd file
is
GroupDescriptorFile
1
Title SK-SZ
Class A1B1
Class A1B2
Class A2B1
Class
A2B2
Variable C
Input S1 A1B1 0.0
Input S2 A1B2
2.0
Input S3 A2B1 3.0
Input S4 A2B2
0.0
The mtx file
is
0.5 -0.5 -0.5 0.5 0
0 0 0
Is it
correct?
Thanks a
lot!
