Abstract

The Cox regression model is the most commonly used regression model for survival
data and sensitive to proportional hazards. In the violation of proportional hazards,
several survival models are suggested. In this study, frailty model was investigated in case
of nonproportional hazards and a numerical example which includes a data of stomach
cancer patients is done to clarify the model.

Keywords

Cox regression model, nonproportional hazards, parametric regression models, frailty model
