Uniform correlation structure and convex stochastic ordering in the PÓlya urn scheme


  • Raffaella Calabrese

    (Dynamics Lab, Geary Institute, University College Dublin)


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.
