In this paper we extend the concept of Competitivity Graph to compare series of rankings with ties ({\em partial rankings}). We extend the usual method used to compute Kendall's coefficient for two partial rankings to the concept of evolutive Kendall's coefficient for a series of partial rankings. The theoretical framework consists of a four-layer multiplex network. Regarding the treatment of ties, our approach allows to define a tie between two values when they are close {\em enough…

A new technique to analyze families of rankings based on sports rankings and, more precisely, on soccer leagues is shown, which gives a generalization of the Kendall's correlation coefficient to more than two rankings.

The pattern of alliances among states is commonly assumed to reflect the extent to which states have common or conflicting security interests. For the past twenty years, Kendall's τ b has been used

### Generalized distances between rankings

• Computer Science

• 2010
This work extends Spearman's footrule and Kendall's tau to those with position and element weights, and shows that a variant of the Diaconis-Graham inequality still holds - the generalized two measures remain within a constant factor of each other for all permutations.

### On rank correlation and the distance between rankings

This work introduces an alternative measure of distance between rankings that corrects this by explicitly accounting for correlations between systems over a sample of topics, and moreover has a probabilistic interpretation for use in a test of statistical significance.

The consensus ranking problem has received much attention in the statistical literature. Given m rankings of n objects the objective is to determine a consensus ranking. The input rankings may
