Stgenreg: A stata package for general parametric survival analysis

Abstract

In this paper we present the Stata package stgenreg for the parametric analysis of survival data. Any user-de_ned hazard function can be speci_ed, with the model estimated using maximum likelihood utilising numerical quadrature. Models that can be _tted range from the Weibull proportional hazards model to the generalized gamma model, mixture models, cure rate models, accelerated failure time models and relative survival models. We illustrate the features of stgenreg through application to a cohort of women diagnosed with breast cancer with outcome all-cause death.
