Intergroup Concordance: Definition and Estimation
提出一个与Kendall组内一致性系数一致的组间一致性系数，调和了两种已有方法，并基于刀切法给出估计和检验程序，适用于多组比较。
A coefficient of intergroup concordance is proposed which is consistent with the concept of intragroup concordance as measured by Kendall's coefficient of concordance (Kendall & Babington Smith, 1939). This approach reconciles the approaches of Schucany & Frawley (1973) and of Hollander & Sethuraman (1978) to the problem of two-group concordance. Estimation and test procedures for the population are based on jackknife procedures. Extension to the problem of multiple intergroup concordance when groups have factorial structure is noted.
