minimum objective function

From: "Ian J. Gowrie" <i.j.gowrie@city.ac.uk> Subject: minimum objective function Date: Wed, 02 Dec 1998 17:19:24 +0000 Dear all, I've a simple(?) question concerning the Minimum Objective Function. Say I have some models and during model building I get the following results: THETA(1) only, objective function = OF1 THETA(2) only, objective function = OF2 THETA(1) and THETA(2). objective function = OF3 Must the following statements be true? OF3 < OF2 OF3 < OF1 I ask this, naturally, because I have a situation where one of these is not true, and I am interested in what the causes may be. Thanks for your time Ian J Gowrie *************************************** Centre for Measurement in Medicine City University London
