Dynamic Random Effects Models for Times Between Repeated Events

We consider recurrent event data when the duration or gap times between successive event occurrences are of intrinsic interest. Subject heterogeneity not attributed to observed covariates is usually handled by random effects which result in an exchangeable correlation structure for the gap times of a subject. Recently, efforts have been put into relaxing this restriction to allow non-exchangeable correlation. Here we consider dynamic models where random effects can vary stochastically over the gap times. We extend the traditional Gaussian variance components models and evaluate a previously proposed proportional hazards model through a simulation study and some examples. Besides, semiparametric estimation of the proportional hazards models is considered. Both models are easily used. The Gaussian models are easily interpreted in terms of the variance structure. On the other hand, the proportional hazards models would be more appropriate in the context of survival analysis, particularly in the interpretation of the regression parameters. They can be sensitive to the choice of model for random effects but not to the choice of the baseline hazard function.

Implications of Model Misspecification in Robust Tests for Recurrent Events

Chronic disease processes often feature transient recurrent adverse clinical events. Treatment comparisons in clinical trials of such disorders must be based on valid and efficient methods of analysis. We discuss robust strategies for testing treatment effects with recurrent events using methods based on marginal rate functions, partially conditional rate functions, and methods based on marginal failure time models. While all three approaches lead to valid tests of the null hypothesis when robust variance estimates are used, they differ in power. Moreover, some approaches lead to estimators of treatment effect which are more easily interpreted than others. To investigate this, we derive the limiting value of estimators of treatment effect from marginal failure time models and illustrate their dependence on features of the underlying point process, as well as the censoring mechanism. Through simulation, we show that methods based on marginal failure time distributions are shown to be sensitive to treatment effects delaying the occurrence of the very first recurrences. Methods based on marginal or partially conditional rate functions perform well in situations where treatment effects persist or in settings where the aim is to summarizee long-term data on efficacy.
