Le tau de Kendall et deux variantes pour mesurer la cohérence de variation entre deux séries ordinales, leurs propriétés et leurs valeurs critiques "honnêtes" [PDF]
Tutorials in Quantitative Methods for Psychology, 2022 A measure of the consistency of variation in a bivariate series of ordinal data, Kendall's tau (\tau) has properties and exhibits distributional characteristics that are distinct from Pearson's r, each coefficient deserving its own interpretation.

Copula Structure Analysis Based on Robust and Extreme Dependence Measures [PDF]
, 2006 In this paper we extend the standard approach of correlation structure analysis in order to reduce the dimension of highdimensional statistical data. The classical assumption of a linear model for the distribution of a random vector is replaced by the ...

Interpreting Kendall’s Tau and Tau-U for single-case experimental designs
Cogent Psychology, 2018 Tau (τ), a nonparametric rank order correlation statistic, has been applied to single-case experimental designs with promising results. Tau-U, a family of related coefficients, partitions variance associated with changes in trend and level.
