In this paper two characterizations of the Pólya distribution are obtained when its contagion parameter is negative. One of them is based on mixtures and the other one is obtained by characterizing a subfamily of the discrete Pearson system.
Mathematics Subject Classification: 60E05 / 60E99
Key words: Pólya distribution / hypergeometric distribution / characterization.
