In this article, we first propose a joint model that consists of a semiparametric multilevel latent trait model (MLLTM) for the multiple lon gitudinal outcomes, and a survival model for event time. The two submodels are linked together by an underlying latent variable. We develop a Bayesian

Advances in Mixture Models - citeseerx.ist.psu.edu

In survival analysis, heterogeneity between individuals is often described by frailty models, where random effects act multiplicatively on the hazard function. This corresponds to a mixture model for survival times. Correlated frailty models (Yashin et al., 1995) are appropriate for clustered survival data, where one often observes correlation
