Bias Of The Cox Model Hazard RatioJournal of Modern Applied Statistical Methods
AbstractThe hazard ratio estimated with the Cox model is investigated under proportional and five forms of nonproportional hazards. Results indicate that the highest bias occurs for diverging hazards with early censoring, and for increasing and crossing hazards under a high censoring rate.
