SpearmanRankCorrelation

As of Version 9.0, SpearmanRankCorrelation has been renamed to SpearmanRho and is part of the built-in Wolfram Language kernel.

SpearmanRankCorrelation[xlist,ylist]

gives Spearman's rank correlation coefficient for the realvalued vectors xlist and ylist.

Details and Options

• To use SpearmanRankCorrelation, you first need to load the Multivariate Statistics Package using Needs["MultivariateStatistics`"].
• Spearman's rank correlation coefficient is a measure of association based on the rank differences between two lists.
• Spearman's is given by , where n=Length[xlist], is the rank difference between and , is the correction term for ties in xlist, and is the correction term for ties in ylist.
• The arguments xlist and ylist can be any realvalued vectors of equal length.
