Spearman-RHO

Spearman's rank correlation coefficient in NodeJS.

In statistics, Spearman's rank correlation coefficient (or Spearman's rho) is a nonparametric measure of statistical dependence between two variables.

It assesses how well the relationship between two variables can be described using a monotonic function. If there are no repeated data values, a perfect Spearman correlation of +1 or −1 occurs when each of the variables is a perfect monotone function of the other. (Wikipedia)
