Testing for zero-modification in count regression models [PDF]

, 2006
Count data often exhibit overdispersion and/or require an adjustment for zero outcomes with respect to a Poisson model. Zero-modified Poisson (ZMP) and zero-modified generalized Poisson (ZMGP) regression models are useful classes of models for such ...

FLOOD REINSURANCE PREMIUM PRICING BASED ON THE STANDARD DEVIATION PRINCIPLE WITH POT-BASED THRESHOLDS FOR MORTALITY AND PROPERTY DAMAGE RISKS

Barekeng
Disasters that occur in Indonesia lead to financial loss. One approach to mitigating the financial impact is through the utilization of natural disaster insurance.

Rank-Poisson Transformation for Use with Count Data in Poisson Regression

AppliedMath
Count outcomes are commonly analyzed using Poisson regression, but empirical data often exhibit overdispersion, excess ties, heaping, or other departures from the Poisson distribution. This paper evaluates a rank-Poisson transformation, denoted poisrank,

A Unified Approach to Some Mixed Poisson Distributions

, 2015
[[abstract]]In this paper we derive a new mixed Poisson distribution which includes the negative binomial, Poisson-Lindley, Poisson-Lomax, Poisson-Beta type II, and Poisson-F distributions.

"On a limiting quasi-multinomial distribution" [PDF]

A random clustering distribution is useful for modeling count data. The present article derives a new distribution of this type from the Lagrangian Poisson distribution, based on the result that any infinitely divisible distribution over nonnegative ...

A priori ratemaking using bivariate poisson regression models [PDF]

In automobile insurance, it is useful to achieve a priori ratemaking by resorting to generalized linear models, and here the Poisson regression model constitutes the most widely accepted basis. However, insurance companies distinguish between claims with

Spatial modelling of claim frequency and claim size in insurance [PDF]

, 2005
In this paper models for claim frequency and claim size in non-life insurance are considered. Both covariates and spatial random e ects are included allowing the modelling of a spatial dependency pattern.

The Poisson–QGamma Distribution: Properties, Estimation Methods, Regression Modeling, and Applications in Engineering Count Data

Stats
Modeling over-dispersed count data is a common challenge in applied statistics, especially in engineering applications where repeated events, system faults, and clustered observations often produce variability beyond that allowed by the classical Poisson
