I am trying to study the correlation between a clinical measurement and FBA metrics. I just wanted to make sure that my design and contrast matrices do what they’re supposed to do.
My design matrix looks like this:
Clinical measurement
gender
demeaned age
6.075
1
3.75
7.215
0
2.75
-0.875
1
10.75
0.83
0
9.75
3.43
0
-5.25
2.205
1
5.75
6.99
1
-5.25
-6.345
1
-8.25
2.79
0
-8.25
-6.855
0
5.75
-11.945
1
-2.25
-3.52
0
-9.25
and my contrast matrix looks like this:
1 0 0
I’m trying to study the correlation of the first column (the clinical measurement) with the FBA metrics (FD, FC and FDC), while correcting for gender and demeaned age. Am I doing this right??
Any input is appreciated. Thanks for the constant support!
Thanks for the help. I did come across your post while searching the forum for a similar question to mine, but I didn’t find what I was looking for. However, upon further digging into the forum, I have come across a post with basically the same question as mine. But thank you anyway for offering your help, very kind of you
