等级相关系数是衡量两个具有有序类别的变量之间关联程度的统计指标。一些著名的秩相关系数是由Goodman和Kruskal（1954，1959）、Kendall（1955）和索默斯（1962）提出的。秩相关方法有几个共同的特点。它们基于计数，并被定义为系数为零表示变量之间“无关联”，值为+1.0或-1.0分别表示“完全一致”或“完全逆一致”。
Rank correlation coefficientsare statistical indices that measure the degree of association between two variables having ordered categories. Some well-known rank correlation coefficients are those proposed by Goodman and Kruskal (1954, 1959), Kendall (1955), and Somers (1962). Rank correlation methods share several common features. They are based on counts and are defined such that a coefficient of zero means “no association” between the variables and a value of +1.0 or -1.0 means “perfect agreement” or “perfect inverse agreement,” respectively.
