two sets of discrete data place the distinct items in the same order, given byrS =1–6Σd2/n(n2–1), where Σd2is the sum of the squares of the differences of ranks between the two orderings andnis the number of items in each. Also called:Spearman's rank-order correlation ...
Spearman Rank-Order Correlation 用法 Spearman秩相关系数(Spearman's rank-order correlation coefficient)是一种非参数的统计量,用于衡量两个变量之间的单调关系。与Pearson相关系数不同,Spearman秩相关系数基于变量的秩次而不是原始数据的值。 Spearman秩相关系数的计算步骤如下: 对每个变量的观测值进行排序,得到每个观...
(2011) found a significant positive Spearman Rank Order Correlation between the P retention and the contents of CaO and Ca in substrates (R2 = 0.51 and 0.43, respectively). Different mainly Ca-rich natural and artificial materials have been suggested for efficient P removal in CWs, such ...
What is the definition of Spearman's rank-order correlation?There are two methods to calculate Spearman's correlation depending on whether: (1) your data does not have tied ranks or (2) your data has tied ranks. The formula for when there are no tied ranks is:...

Spearman Rank Order 相关系数 是变量排序后的简单相关系数。 举例如下: x=(0.8, 1.2, 1.2, 2.3, 18) y=(3, 9, 6, 11, 15) 那么x 与 y 之间的相关系数为 : [(1-3)*(1-3)+(2.5-3)*(3-3)+(2.5-3)*(2-3)+(4-3)*(4-3)+(5-3)*(5-3)] / ...

• Spearman’s correlation is then given by • Where d i is the difference between the ith rank for x and the ith rank for y • It turns out that this formula is algebraically equivalent to using the Pearson product moment correlation on the ranks • And this in turn provi...
