Weighting in NONMEM

From: Yaning Wang Subject: [NMusers] Weighting in NONMEM Date:Mon, 02 Jun 2003 10:26:11 -0400 Hi all: This may be a little bit distracting from the main question for this thread (reference to: 99jun022003), but could anyone explain why a weighting like W=SQRT(THETA(5)**2+THETA(6)**2/F**2) used by Justin is equivelant to a combination error model as NONMEM guide suggested? What is the advantage of this form to the standard combination error model? Any suggestion is appreciated. -- Yaning Wang Department of Pharmaceutics College of Pharmacy University of Florida
