Modelling count data is one of the most important issues in statistical research. In this paper, a new probability mass function is introduced by discretizing the continuous failure model of the Lindley distribution. The model obtained is over-dispersed and competitive with the Poisson distribution to fit automobile claim frequency data. After revising some of its properties a compound discrete Lindley distribution is obtained in closed form. This model is suitable to be applied in the collective risk model when both number of claims and size of a single claim are implemented into the model. The new compound distribution fades away to zero much more slowly than the classical compound Poisson distribution, being therefore suitable for modelling extreme data.read more

Discrete Extension of Poisson Distribution for Overdispersed Count Data: Theory and Applications
TL;DR: In this paper , a new one-parameter discrete probability distribution is introduced for overdispersed count data based on a combining approach, and the important statistical properties can be expressed in closed forms including factorial moments, moment generating function, dispersion index, coefficient of variation and coefficient of skewness.
On Type-II Hybrid Censored Lindley
TL;DR: In this paper, the authors deal with the inferential study of Lindley distribution when the data are type-II hybrid censored and derive the maximum likelihood estimate of the parameter with its standard error.

A new method for adding a parameter to a family of distributions with application to the exponential and Weibull families
Albert W. Marshall,Ingram Olkin +1 more
TL;DR: In this article, a new way of introducing a parameter to expand a family of distributions is introduced and applied to yield a new two-parameter extension of the exponential distribution which may serve as a competitor to such commonly-used twoparameter families of life distributions as the Weibull, gamma and lognormal distributions.
