摘要
两个评估者对 n 个观察对象逐一评估它们属于 C 个类别中的哪一类,结果类别表达在 C×C 列联表。该文介绍 C 个类别 Kappa 量的分解,并讨论两个类别的合并,Kappa 量增大的充分必要条件。
When two assigners independently classity each of n objects into one of C categories,the resulting classifications can be displayed in an C×C contingency table.This paper is to present the division of Kappa Statistics for each categories and to prove the sufficient and necessary conditions for enlarge Kappa statistics when two cotegories are combined.
