摘要
两个评估者对n个观察对象,逐一评估它们属于C个类别中那一个类别,所得资料可表达成C×C列联表形式。Kappa检验主要检验配对计数资料C×C表主对角线上的计数值是否显著地大于其期望值。本文目的在于导出Kappa检验的确切概率计算法。
When 2 assignees working independently classified each of the objects into one of the C categories, the informations obtained could be displayed in a C×C contingency table. Kappa statistics focuses on the counts in the major diagonal of the C×C table, testing if the diagonal counts were significantly higher than those expected (by chance alone). The primary purpose of this paper was to work out a method of calculation of the exact probability for kappa test.
