I was reading articles
(http://www.lexjansen.com/pharmasug/2003/statisticspharmacokinetics/sp013.pdf( A SAS Macro to Automate The Covariance Structure Determination in
Repeated Measures Data Analysis with Mixed Procedure Don (Dongguang) Li,
NCIC-CTG at Queenâ€™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.
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.
