The estimated frequency of zero for a mixed Poisson distribution

Ian R. Harris

Statistics & Probability Letters, 1991, vol. 12, issue 5, 371-372

Abstract: The estimated frequencies of a mixed Poisson distribution are investigated. The frequencies are calculated using non-parametric maximum likelihood estimation. It is shown that the estimated frequency of zero is always greater than the observed frequency, and thus is biased.
