‘SPEARMAN'S RHO’ AND THE MATCHING PROBLEM
D. E. Barton, F. Noble David · British Journal of Statistical Psychology · 1956
Abstract. The following paper describes a possible model, based on a distortion of the random sequence, which may be used as a hypothesis alternative to the hypothesis of randomness. The model is applied to the case of “Spearman;s rho” but may be adopted as an alternative to the random sequence for any bivariate criterion.
