摘要：The Cox proportional hazards model technique is demonstrated in an analysis of the longevity of Broadway shows. The necessity of using the Cox proportional hazards model to identify the factors associated with show longevity becomes clear by comparison to an ordinary linear regression analysis. Emphases are given to the model interpretation, including residual analysis, tests for the proportional hazards assumption, and fitting the stratified proportional hazards model. The intended audience consists of all applied statisticians who may con-sider using the Cox proportional hazards model. A basic to intermediate level of statistical analysis background is needed to understand the case.
