Extended Truncated Tweedie - Poisson Model
It has been argued that by truncating the sample space of the negative binomial and of the inverse Gaussian-Poisson mixture models at zero, one is allowed to extend the parameter space of the model. Here that is proved to be the case for the more general three parameter Tweedie-Poisson mixture model. It is also proved that the distributions in the extended part of the parameter space are not th...
متن کاملOn Poisson–Tweedie mixtures
*Correspondence: [email protected] 1Department of Mathematics, Ohio University, Athens, OH, USA Full list of author information is available at the end of the article Abstract Poisson-Tweedie mixtures are the Poisson mixtures for which the mixing measure is generated by those members of the family of Tweedie distributions whose support is non-negative. This class of non-negative integer-valued ...
متن کاملevaluation of Tweedie exponential dispersion model densities ∗
Exponential dispersion models, which are linear exponential families with a dispersion parameter, are the prototype response distributions for generalized linear models. The Tweedie families are those exponential dispersion models with power mean-variance relationships. The normal, Poisson, gamma and inverse Gaussian distributions are Tweedie families. Apart from these special cases, Tweedie di...
متن کاملtweeDEseq: analysis of RNA-seq data using the Poisson-Tweedie family of distributions
This document gives an overview of the R package tweeDEseq, which provides statistical procedures for testing differential expression in RNA-seq count data. In fact, these procedures could be applied, in principle, to any kind of count data, other than RNA-seq. The tweeDEseq package offers a function for normalizing count data which actually calls other functions for that purpose from the edgeR...
متن کاملLearning the beta-Divergence in Tweedie Compound Poisson Matrix Factorization Models
In this study, we derive algorithms for estimating mixed β-divergences. Such cost functions are useful for Nonnegative Matrix and Tensor Factorization models with a compound Poisson observation model. Compound Poisson is a particular Tweedie model, an important special case of exponential dispersion models characterized by the fact that the variance is proportional to a power function of the me...
