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...

主要看样本量,如果样本量较大,mann-kendall的统计量近似正态分布,标准化后就可以按标准正态的方法计算;如果样本量较小,"Rank Correlation Methods" (4th Edition)1970 当时给出了具体的计算公式。可以看一下stats kendalltau的源码,还蛮具体的 2021-09-21 回复喜欢 Kristov Pearson, Spearman这两个相关系...
Kendall相关系数(Kendall rank correlation coefficient)是基于排序统计量的一种非参数检验方法,由英国统计学家MauriceKendall在1938年提出。Kendall相关系数衡量的是两组数据在排序上的相似性,而不是它们的原始数值。 # 2.计算公式 Kendall相关系数用希腊字母τ(tau)表示,计算公式如下: \tau = \frac{N_c - N_d}...

Kendall's Tau Correlation Coefficient: Ø Definition: Measures the rank correlation between two variables without assuming a linear relationship. Ø Advantages: Robust, insensitive to outliers, suitable for ordered data. Ø Formula: Kendall's táu(不支持希腊字母QAQ) ...
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 Tau is a nonparametric measure of the degree of correlation. It was introduced by Maurice Kendall in 1938 (Kendall 1938 ). Kendall's Tau measures the strength of the relationship between two ordinal level variables. Together with Spearman's rank correlation coefficient, they are two ...
