Abstract
Lifetime data classified according to categorical variables under the proportionality of the hazard functions of response variables for vari ous treatment combinations is assumed. The proposed model is a combina tion of Cox's proportional hazards model and ANOVA model. The existenc e of a solution to the marginal likelihood function is examined for th e case of 2x2 two-way classification. We provide an easily verifiable condition for the existence of a unique estimate. (C) 1997 Elsevier Sc ience Inc.
