New statistical test for Frechet regression on Bures-Wasserstein manifolds proposed

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new statistical test for analyzing partial effects in Fréchet regression, specifically for data residing on Bures-Wasserstein manifolds. The proposed test statistic approximates a V-statistic under the null hypothesis, with its limiting distribution being a mixture of chi-squared variables. This distribution is determined by the eigenvalues of an integral operator linked to a reproducing kernel Hilbert space kernel. The study validates the test's asymptotic properties and consistency, and its effectiveness is demonstrated through simulations and an application to single-cell RNA-seq data to examine the influence of age on gene co-expression structure.

    Test of partial effects for Frechet regression on Bures-Wasserstein manifolds

    arXiv:2506.23487v2 Announce Type: replace-cross Abstract: We propose a novel test for assessing partial effects in Fr\'echet regression with responses lying on the Bures-Wasserstein manifold. Under the null hypothesis, we show that the statistic admits a degenerate V-statistic ap…
