Series evaluation of Tweedie exponential dispersion model densities [PDF]
Exponential dispersion models, which are linear exponential families with a dispersion parameter, are the prototype response distributions for generalized linear models. The Tweedie family comprises those exponential dispersion models with power mean-variance relationships.

Statistical procedures based on exponential scores [PDF]
Many statistical models have been proposed in which underlying exponential distributions are assumed. Applications of such models occur in a large number of areas, for example in reliability and life-testing investigations and in the study of the ...

An analysis of spatial dispersal in Ceratitis capitata in an orchard of the ‘Palmer’ mango using McPhail traps1 [PDF]
The aim of this study was to analyse patterns of spatial dispersal in Ceratitis capitata using two types of attractive traps and propose a predictive model of pest dispersal with the aim of determining management zones for decision-making. The experiment

Modeling a Wave on Mild Sloping Bottom Topography and Its Dispersion Relation Approximation
Linear wave theory is a simple theory that researchers and engineers often use to study a wave in deep, intermediate, and shallow water regions. Many researchers mostly used it over the horizontal flat seabed, but in actual conditions, sloping seabed ...

Tail Conditional Expectations for Exponential Dispersion Models [PDF]
There is a growing interest in the use of the tail conditional expectation as a measure of risk. For an institution faced with a random loss, the tail conditional expectation represents the conditional average amount of loss that can be incurred in a fixed period, given that the loss exceeds a specified value.

New exponential dispersion models for count data: the ABM and LM classes [PDF]
In their fundamental paper on cubic variance functions (VFs), Letac and Mora (The Annals of Statistics, 1990) presented a systematic, rigorous and comprehensive study of natural exponential families (NEFs) on the real line, their characterization through their VFs and mean value parameterization.
