WebSpearman’s rank correlation: A non-parametric measure of correlation, the Spearman correlation between two variables is equal to the Pearson correlation between the rank scores of those two variables; while Pearson’s correlation assesses linear relationships, Spearman’s correlation assesses monotonic relationships (whether linear or not). Webapproach is to use a test statistic based on the Fisher z-transform of r [6]. For any -1 < r < 1, the Fisher z-transform of r is given by: z(r)=tanh-1 r =ln((1+r)/(1-r))/2, (3) which is asymptotically distributed as (tanh ,1 2 ) z N − ρσ, where denotes ρ the population value of the PCC and σ2 z denotes the asymptotic variance of z(r).
