Abstract

This analysis of the PÓlya urn scheme focuses on proving two new important results. First, the correlation structure between draws of a PÓlya urn scheme is uniform. Second, fixing the number of draws and the composition of the urn, a convex stochastic ordering is induced by the number of balls replaced into the urn.
