Testing for homogeneity of several functional variables via multiple maximum variance discrepancy

This paper adresses the problem of testing for the equality of k probability distributions on Hilbert spaces, with k 2. We introduce a generalization of the maximum variance discrepancy called multiple maximum variance discrepancy (MMVD). Then, a consistent estimator of this measure is proposed as test statistic, and its asymptotic distribution under the null hypothesis is derived. A simulation study comparing the proposed test with existing ones is provided
