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...
(Simulation) Introduction This procedure analyzes the power and significance level of Spearman’s Rank Correlation significance test using Monte Carlo simulation. This test is used to test whether the rank correlation is non-zero. For each scenario that is set up, two simulations are run. One ...
This guide will tell you when you should use Spearman's rank-order correlation to analyse your data, what assumptions you have to satisfy, how to calculate it, and how to report it. If you want to know how to run a Spearman correlation in SPSS Statistics, go to our Spearman's ...

for example i want to calculate correlation with period 4 so i have to perform 12 windowing. i have to get order and value rank for each window and calculate the correlations. I Already built the code, but it was too slow, because i have to perform up to 500000 series ...
