Abstract

We provide a Central Limit Theorem for the Monge-Kantorovich distance between two empirical distributions with size nn and mm, Wp(Pn,Qm)W_p(P_n,Q_m) for p>1p>1 for observations on the real line, using a minimal amount of assumptions. We provide an estimate of the asymptotic variance which enables to build a two sample test to assess the similarity between two distributions. This test is then used to provide a new criterion to assess the notion of fairness of a classification algorithm.
