Frailty Models in Survival Analysis

Mehr zum Buch

Focusing on the practical application of frailty modeling, this book offers an accessible overview of statistical techniques for nonspecialists. It delves into univariate frailty models and their ability to address unobserved heterogeneity, while also examining correlated frailty models as advanced extensions. The author compares frailty and copula models, tackles associated challenges, and presents parametric and semiparametric models through both frequentist and Bayesian perspectives. Additionally, it provides guidance on applying these models to real data using R, SAS, and Stata.
