Some new characterizations of the geometric distribution are studied. A generalization of the characterization by the well-known 'lack-of-memory' property is given together with some closely related ...

Biologists have recently explored the distribution of the butterfly Iolana iolas, one of the endangered species in the Madrid region whose population dynamics are determined by its host plant. The ...

Some generalizations of the geometric distribution are derived by length-biasing some generalized versions of the log-series distribution. Moments and maximum likelihood estimates for the parameters ...
