We derive a beautiful series expansion for Spearman's rho, ρ(θ) of the Ali-Mikhail-Haq (AMH) copula with paramater θ which is also called α or θ. Further, via experiments we determine the cutoffs to be used for practically fast and accurate computation of ρ(θ) for all θ∈ [...
Spearman's rho, r s , is a correlation measure of association based on ranks of scores rather than raw scores. It is applicable if either or both variables are direct rankings or only ordinal. It is also applicable when both variables are metric but not normally distributed, or when the ...

A statistic used as a measure of correlation in nonparametric statistics when the data are in ordinal form; a product moment correlation coefficient. Also known as Spearman's rho. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc....
In a nonparametric (distribution-free) approach to the correlation between two sets of measurements made on the same individuals, each set may be ranked in order of magnitude. The standard (Pearson) product-moment correlation coefficient is calculated on the two sets of ranks. Simple formulae are...
