Abstract

GHREG is a computer program for modeling short-term and long-term effects of potentially time-dependent covariates on right-censored failure time data in cohort studies. Standard statistical analysis of failure time data using the Cox model can yield very misleading results when the proportional hazards assumption of constant relative risk is violated. GHREG implements valid and efficient statistical methods that allow non-constant hazard ratios over time. The current release performs semiparametric regression analysis of right-censored failure time data with time-independent covariates.
