资源简介：
According to Landis the kappa coefficient (k) was rated as follows:Poor (kSubstantial (k = 0.61–0.80), Almost Perfect (k = 0.81–1.00).Disagreements were weighted by 1– {(i–j)/(k–1)}2 where i and j index the rows and columns of the ratings by the two raters and k is the maximum number of possible ratings.
根据Landis提出的科恩卡帕系数（Kappa Coefficient，记为k）的评级标准如下：不佳（k < 0.60）、显著（k = 0.61–0.80）与近乎完美（k = 0.81–1.00）。两名评分者的评分不一致时，权重计算方式为1 - [(i - j)/(k - 1)]²，其中i与j分别代表两名评分者的评分矩阵的行与列索引，k为所有可能评分等级的最大数量。
