PGMHAZ8: Stata module to estimate discrete time (grouped data) proportional hazards models
pgmhaz8 estimates by ML two discrete time (grouped data) proportional hazards regression models, one of which incorporates a gamma mixture distribution to summarize unobserved individual heterogeneity (or 'frailty'). Covariates may include regressor variables summarizing observed differences between persons (either fixed or time-varying), and variables summarizing the duration dependence of the hazard rate. With suitable definition of covariates, models with a fully non-parametric specification for duration dependence may be estimated; so too may parametric specifications. pgmhaz8 thus provides a useful complement to stcox (for continuous survival time data), and related programs.
