Hi,
I am trying to figure out the contrasts to use for a study. I am comparing age matched patients and controls (all female). The FSGD file has 4 columns, but I'm not sure how to make an appropriate contrast matrix. Any guidance would be appreciated. I can't seem to find an applicable example on the wiki.
Thanks, Allison
