Diagnostics for Cox’s Proportional Hazards ModelAlthough Cox’s proportional hazards model is applied so often, diagnostic methods are not well known to non-expert users. Latest results suggest that individually scaled Schoenfeld residuals, dfbetas and added variable plots should be provided for assessing the model. Most of these methods are absent from widely used packages.

Foreknowledge

An Example of Optimal Design in Accelerated ExperimentsThe AFT (Accelerated Failure Time) model is considered in order to study the opportunity of optimal design in accelerated experiment. Semiparametric estimation is proposed for a step stress experiment. Monte Carlo simulations are used to evaluate a strategy of optimal design for finite samples.

Aspects of Multivariate Aging in Exchangeable Frailty ModelsWe consider some notions of multivariate aging, suitable to analyze vectors of exchangeable lifetimes: such notions are used to describe some basic aspects of a specific heterogeneity model, characterized by exchangeable frailties
