External Email - Use Caution Hello FS experts
Thank you for your kind response. This is regarding my previous mail. I think we need to talk about the design matrix X first (sorry, I did not look at your xlsx file; I think it's probably better to send simple csv files if at all). I attached longitudinal data in csv format. Besides the covariates that you mention, the matrix needs to contain an intercept, a variable for ?time?, a variable for ?group? (assuming you have a control group also), and a group-by-time interaction term in order to asses differential change over time (again, if you have a control group). I do not have a control group. Right now I have only schizophrenia patients who underwent 2 scans: the first is the baseline and the second one is after 3 months of yoga therapy. Wish to know how can I proceed with my available data. Just to make sure: ?age? should be ?age at baseline? (i.e. constant across time per subject), otherwise, it will be confounded with time. Yes, I used the same across the study. Could you review (and possibly adapt) your design matrix X with respect to which columns it contains, and write it in the reply? I tried but couldn't get there. Looking forward to your response. Thanks, Vittal
