Subject: [NMusers] covariate model building:  forward inclusion and backward elimination
Date: Mon, 30 Oct 2006 10:22:30 -0500

Hello NONMEM users,

This is question about forward inclusion and backward elimination.  Obviously, backward elimination
should be done using NONMEM.  Some scientist apply NONMEM to do forward inclusion.  Some other
scientists use SAS or S-plus to run regression analysis on Bayesian estimates while including
covariates in the model.  Is that appropriate to use SAS or some other software instead of NONMEM
during the forward inclusion step?

Thank you,
