comparing theta's

From: "Bonate, Peter, Quintiles" <pbonate@qkcm.quintiles.com> Subject: comparing theta's Date: Thu, 25 Mar 1999 07:23:39 -0600 I have three groups of data on the same drug that were analyzed using the same models in NONMEM. Each model was analyzed separately. I have theta's, se(theta), and covariance matrices for all three groups. Does anyone know of a test that will let me test whether the theta's are the same for all groups? Thanks. PETER L. BONATE, PhD.
