The logarithmic poisson gamma distribution: A model for leadtime demand

Naval Research Logistics Quarterly, 1982
AbstractThis paper considers an inventory system in which demand occurrences arise according to a stationary Poisson process, demand sizes at each occurrence follow a logarithmic distribution, and leadtimes are random variables with the gamma distribution.

The Poisson Gamma distribution for wind speed data

AIP Conference Proceedings, 2016
The wind energy is one of the most significant alternative clean energy source and rapidly developing renewable energy sources in the world. For the evaluation of wind energy potential, probability density functions (pdfs) are usually used to model wind speed distributions.

A class of flat prior distributions for the Poisson‐gamma hierarchical model

Statistica Neerlandica, 2019
A wide class of prior distributions for the Poisson‐gamma hierarchical model is proposed. Prior distributions in this class carry vague information in the sense that their tails exhibit slow decay. Conditions for the propriety of the resulting posterior density are determined, as well as for the existence of posterior moments of the Poisson rate of ...

On the compound Poisson-gamma distribution

Kybernetika, 2011
Summary: The compound Poisson-gamma variable is the sum of a random sample from a gamma distribution with sample size an independent Poisson random variable. It has received wide ranging applications. We give an account of its mathematical properties including estimation procedures by the methods of moments and maximum likelihood.

Spatial Reconstruction of Precipitation Fields Using the Effective Distribution Methodology with Compound Poisson Gamma Marginals

Modeling daily precipitation remains a challenge due to the intermittent, non-Gaussian, and spatially dependent structure of the process.We propose a novel stochastic spatial precipitation generator which uses the compound Poisson gamma distribution (CPG) to handle simultaneously the intermittency and non-Gaussianity of daily precipitation combined ...
