2.2.2 Correlation and Rank Correlation The correlation coefficient (CC) between two random variables is a measure of the strength of their linear relationship. It is closely linked to the concept of covariance and is defined as (2.13)CC=ρxy=σxyσxσy=1N−1∑i=1Nxi−X―σxyi−Y―...

Goodman and Kruskal’s Gamma是另一种常用的rank correlation方法,它用于衡量两个变量之间的等级关系。它的计算公式如下: γ = (P - Q) / (P + Q) 其中,γ表示Goodman and Kruskal’s Gamma系数,P表示两个变量之间的同向对数,Q表示两个变量之间的反向对数。 Goodman and Kruskal’s Gamma通常用于衡量两个...
Within the bounds of a general theory of rank correlation two particular measures have been adopted widely: Spearman's rank correlation coefficient, , in which ranks replace variates in Pearson's product-moment correlation calculation; and Kendall's , in which the disarray of x-ordered data due ...
1. Spearman's Rank Correlation Coefficient: Spearman's Rank Correlation Coefficient (rho)可以用于衡量两个变量之间的单调关系。计算公式如下: rho = 1 - (6 * sum(d^2))/(n*(n^2-1)) 其中,d是两组数据中对应值的差,n是数据集的大小。 2. Kendall's Rank Correlation Coefficient: Kendall's Rank...
