Abstract:
|
Random effects or frailty models have become very useful in modeling dependence between individual survival times or between survival times in multistate modeling. A number of models have been proposed for the frailties in the literature but it is difficult in practice to pick between these models. In this presentation we present a general method to asses the goodness of fit of the choice of the frailty distribution. This technique, which is essentially a goodness of fit test for the copula, is based on a comparison between a distribution free estimator of the copula and the postulated copula. The method is available for any copula and does not involve the marginal survival functions.
