Kendall's rank correlation tau between two variables, in the presence of a third blocking variable, is defined. An estimator of the common tau within the blocks is used to test conditional independence of the two variables, given the blocking variable. An application is presented.
定义了在存在第三个阻断变量的情况下，两个变量之间的肯德尔等级相关系数τ。使用块内公共τ的估计量来检验给定阻断变量时两个变量的条件独立性。给出了一个应用实例。
