Two q-analogues of the hyper-Poisson distribution are derived via the Heine and Euler q-analogues of the Poisson distribution. The paper examines some of their properties and provides models based on mixtures of other q-distributions. Group-size models are also given. (C) 2002 Elsevier Science B.V. All rights reserved.
