Abstract:
|
We propose a procedure for selection of mixed effects models for survival analysis. The procedure is based on a recently developed method, called fence method (Jiang et al. 2006). The idea involves a procedure to isolate a subgroup of what are known as correct models (of which the optimal model is a member). While the current model selection procedures for survival analysis are mostly Bayesian, our procedure provides an alternative approach.In particular, we apply the method to proportional hazards models with random effects. The results of a Monte Carlo simulation and the analysis of the Framingham Heart Study data are reported.
