May I request someone to explain (short summary) the Covariance structure and Fixed and Random effects in Proc Mixed? How to interpret 'covariance paramater estimates' in output?
Thanks!
A short summary is impossible. I highly recommend you read the book SAS for Mixed Models, 2nd edition (2006), by Littell et al.
Thank you, Larry. That is the best answer that can be given for this question.
