Flexible Tweedie regression models for continuous data
Wagner H. Bonat, Célestin C. Kokonendji
Tweedie regression models provide a flexible family of distributions to deal with non-negative highly right-skewed data as well as symmetric and heavy tailed data and can handle co…
Extended Poisson-Tweedie: properties and regression models for count data
Wagner H. Bonat, Bent Jørgensen, Célestin C. Kokonendji +2
We propose a new class of discrete generalized linear models based on the class of Poisson-Tweedie factorial dispersion models with variance of the form , where is the…
Likelihood analysis for a class of spatial geostatistical compositional models
Ana Beatriz Tozo Martins, Wagner Hugo Bonat, Paulo Justiniano Ribeiro Junior
We propose a model-based geostatistical approach to deal with regionalized compositions. We combine the additive-log-ratio transformation with multivariate geostatistical models wh…
