2个统计量（kappa和加权kappa）可用于测量2名评分员在名义量表上的一致性。这两个统计量的标准误差公式在高估的方向上是错误的，因此它们的使用导致保守的显著性检验和置信区间。给出了近似大样本方差的有效公式，并用数值例子说明了其计算。（PsycInfo数据库记录（c）2016阿帕，保留所有权利）
2 statistics, kappa and weighted kappa, are available for measuring agreement between 2 raters on a nominal scale. Formulas for the standard errors of these 2 statistics are in error in the direction of overestimation, so that their use results in conservative significance tests and confidence intervals. Valid formulas for the approximate large-sample variances are given, and their calculation is illustrated using a numerical example.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
