论文摘要
我们考虑二进制组指标和正在研究的连续变量之间的肯德尔TAU度量，以制定彻底的两样本比较程序。该措施是危害比率的有用替代方法，其适用性取决于比例危害假设。对于正确的审查数据，我们提出了一个加权对数统计统计量，其权重适合审查分布并开发派生估计器的理论属性。在没有审查的情况下，提出的估计器将减少为WMW统计量。提出的方法用于分析几个数据示例。
We consider a Kendall's tau measure between a binary group indicator and the continuous variable under investigation to develop a thorough two-sample comparison procedure. The measure serves as a useful alternative to the hazard ratio whose applicability depends on the proportional hazards assumption. For right censored data, we propose a weighted log-rank statistic with weights adapted to the censoring distributions and develop theoretical properties of the derived estimators. In absence of censoring, the proposed estimator reduces to the WMW statistic. The proposed methodology is applied to analyze several data examples.
