Rank–Polyserial Correlation: A Quest for a “Missing” Coefficient of Correlation

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
In the typology of coefficients of correlation, we seem to miss such estimators of correlation as rank–polyserial (RRPS) and rank–polychoric (RRPC) coefficients of correlation. This article discusses a set of options as RRP, including both RRPS and RRPC.

Maximal Rank Correlation [PDF]

open access: yesIEEE Communications Letters, 2016
Based on the notion of maximal correlation, we introduce a new measure of correlation between two different rankings of the same group of items. Our measure captures various types of correlation detected in previous measures of rank correlation like the Spearman correlation and the Kendall tau correlation.

On rank correlation and the distance between rankings [PDF]

open access: yesProceedings of the 32nd international ACM SIGIR conference on Research and development in information retrieval, 2009
Rank correlation statistics are useful for determining whether a there is a correspondence between two measurements, particularly when the measures themselves are of less interest than their relative ordering. Kendall's - in particular has found use in Information Retrieval as a "meta-evaluation" measure: it has been used to compare evaluation measures,
