28 Mei 2020 · In the context of hazard models for time to event outcomes, such random effects are called frailties, and the resulting models are called frailty models. In this tutorial, we study frailty models for survival outcomes.

3 Jan 2018 · The concept of frailty was first introduced by Vaupel et al. (1979) (Demography 16:439–454, 1979) to account for the impact of individual heterogeneity in univariate (independent) survival data . In this chapter, we introduce the frailty model, an extension of the Cox PH model, for analyzing correlated survival data .

In frailty models, the dependence is expressed in terms of a random effect, called the frailty. Frailty models have been used with both Cox proportional haz-ards model and the accelerated failure time model. This paper reviews recent developments in the area of frailty models in a variety of settings.
Frailty models provide a powerful tool to analyse clustered survival data. In contrast to the large number of research publications on frailty models, relatively few statistical software packages contain frailty models.
