RE: How to use "age" as covariates?
Hi CONN-ers!
I have a similar question, but want to make sure I'm not over-generalizing to my data.
I have a group comparison between patients and controls and I'd like to see the effect of variables that are not present in the control group (e.g., lesion size and severity). I have set up the contrast as [1 0 -1] for 'control' 'patient' and 'lesion size'. Am I way off? I am hoping to be able to say something like: As lesion size increases, the difference in connectivity between groups increases for these connections. I've looked at the calculator for one of the connections, and this seems to be the case. I just want to make sure the way I've set up the contrast is legit.
Thanks!
