Erika Banzato, Monica Chiogna, Vera Djordjilović, Davide Risso · Statistics & Probability Letters · 2022
This work defines a new correction for the likelihood ratio test for a two-sample problem within the multivariate normal context. This correction applies to decomposable graphical models, where testing equality of distributions can be decomposed into lower dimensional problems.
