Thank you for your help.
I was reading articles
(http://www.lexjansen.com/pharmasug/2003/statisticspharmacokinetics/sp013.pdf[1]( A SAS Macro to Automate The Covariance Structure Determination in
Repeated Measures Data Analysis with Mixed Procedure Don (Dongguang) Li,
NCIC-CTG at Queen’s University, Kingston, ON, Canada.) Please, if posible could you send complete code to me, my aim is to see both all covariance structures and fit statistics on the same table and to view minimum value.
what I can add to the under code, that I can see the fit statistics all of
the covariance structures.
Please
I will appricate if you can help me what code do I add to see all
covariance structure and fit statistics.
Thank you for your help.
