Abstract
A discrete distribution associated with a pure birth process starting with no individuals, with birth rates λn=λ forn=0, 2, …,m−1 and λn forn≥m is considered in this paper. The probability mass function is expressed in terms of an integral that is very convenient for computing probabilities, moments, generating functions and others. Using this representation, the mean and the k-th factorial moments of the distribution are obtained. Some nice characterizations of this distribution are also given.
