www.sas.comCompeting-risks analysis extends conventional survival analysis. For the latter, statistical methods such as the Kaplan-Meier estimate, the log-rank test, and the Cox regression are widely used in many applications. Although the log-rank test and the Cox regression can be adapted with minimal effort to make inferences about the cause-specific

The life-table estimator is a grouped-data analog of the Kaplan-Meier estimator. The procedure can also compute the Breslow estimator or the Fleming-Harrington estimator, which are asymptotic
