在统计学中,肯德尔秩相关系数(Kendall rank correlation coefficient)通常称为肯德尔 τ 系数(以希腊字母 τ,tau 命名),是一种用于测量两个测量量之间的序数关联的统计数据。τ 检验是一种基于 τ 系数的统计依赖性非参数假设检验。 它是秩相关的度量:按每个量排序时数据排序的相似性。 直观地讲,当观测值在两个...

结果:属于等级相关系数。排序一致,则为1, 排序完全相反则为-1。 python3.6应用 : a) Dataframe.corr(method='kendall'), 返回相关关系矩阵 b) from scipy.stats import kendalltau kendalltau(x, y) 返回系数和P值 编辑于 2025-01-14 16:32・IP 属地上海 ...
Kendall's tau-b等级相关系数:用于反映分类变量相关性的指标,适用于两个分类变量均为有序分类的情况。对相关的有序变量进行非参数相关检验; 取值范围在-1-1之间,此检验适合于正方形表格;
The interpretation of Kendall’s tau in terms of the probabilities of observing the agreeable (concordant) and non-agreeable (discordant) pairs is very direct. In most of the situations, the interpretations of Kendall’s tau and Spearman’s rank correlation coefficient are...
Kendall’s rank correlation tau data: exer and smoke z = 1.3694, p-value = 0.1709 alternative hypothesis: true tau is not equal to 0 sample estimates: tau 0.083547 The same can be achieved with the latest version of rpudplus. We begin with the function rpucor, which now uses Kendal...
