Restricted generalized poisson regression model

Communications in Statistics - Theory and Methods, 1993
The family of generalized Poisson distribution has been found useful in describing over-dispersed and under-dispersed count data. We propose the use of restricted generalized Poisson regression model to predict a response variable affected by one or more explanatory variables.

Estimation in the Generalized Poisson Model via Robust Testing

Metrika, 2002
An estimation method is presented which compromises robust efficiency with computational feasibility in the case of the generalized Poisson model. The formal setup is built on flexible nonparametric extensions of the underlying model. The estimation efficiency is expressed via minimax properties of tests resulting from expansions of estimators.

The Poisson Generalized Linear Failure Rate Model

Communications in Statistics - Theory and Methods, 2013
We formulate a new cure rate survival model by assuming that the number of competing causes of the event of interest has the Poisson distribution, and the time to this event has the generalized linear failure rate distribution. A new distribution to analyze lifetime data is defined from the proposed cure rate model, and its quantile function as well as

Estimation of the Characteristics of the Jumps of a General Poisson-Diffusion Model

Scandinavian Actuarial Journal, 2004
We consider a filtered probability space with a standard Brownian motion W, a simple Poisson process N with constant intensity λ>0, and we consider the process Y such that Y 0∈ℝ and where a, σ are predictable bounded stochastic processes, and γ is a predictable process which is bounded away from zero. A discrete record of n+1 observations {Y 0, Y t 1 ,

On some models leading to the generalized poisson distribution

Communications in Statistics - Theory and Methods, 1988
A new generalization of the Poisson distribution was given by Consul and Jain (1970, 73). Since then more than twenty papers, written by various researchers, have appeared on this model under the titles of Generalized Poisson Distribution (GPD), Lagrangian Poisson distribution or modified power series distribution. Here the author provides two physical
