Abstract

Discrete multivariate distributions Logconcavity Multivariate Pólya–Eggenberger distribution Strong unimodality
New sufficient conditions that ensure the strong unimodality of multivariate discrete distributions are obtained by the use of a special simplicial subdivision of multidimensional space. Strong unimodality of multivariate Pólya–Eggenberger distribution is shown.
