Survival Analysis Part IV: Further concepts and methods in survival analysis [PDF]

British Journal of Cancer, 2003
Most analyses of survival data use primarily Kaplan-Meier plots, logrank tests and Cox models. We have described the rationale and interpretation of each method in previous papers of this series, but here we have sought to highlight some of their limitations. We have also suggested alternative methods that can be applied when either the data or a given

Informed Bayesian survival analysis

BMC Medical Research Methodology, 2022
AbstractBackgroundWe provide an overview of Bayesian estimation, hypothesis testing, and model-averaging and illustrate how they benefit parametric survival analysis. We contrast the Bayesian framework to the currently dominant frequentist approach and highlight advantages, such as seamless incorporation of historical data, continuous monitoring of ...

Nonparametric Inference in Mixture Cure Models

Proceedings, 2018
A completely nonparametric method for the estimation of mixture cure models is proposed. Nonparametric estimators for the cure probability (incidence) and for the survival function of the uncured population (latency) are introduced.
