Multivariate models for correlated count data
(2013-04-18)
In this study, we deal with the problem of overdispersion beyond extra zeros for a collection of counts that can be correlated. Poisson, negative binomial, zero-inflated Poisson and zero-inflated negative binomial distributions ...

Beta-binomial/gamma-poisson regression models for repeated counts with random parameters
(Brazilian Statistical Association, 2011-07)
Beta-binomial/Poisson models have been used by many authors to model multivariate count data. Lora and Singer [Stat. Med. 27 (2008) 3366-3381] extended such models to accommodate repeated multivariate count data with ...
A multivariate Poisson deep learning model for genomic prediction of count data

A Poisson mixed model with nonnormal random effect distribution
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In this paper, we propose a random intercept Poisson model in which the random effect is assumed to follow a generalized log-gamma (GLG) distribution. This random effect accommodates (or captures) the overdispersion in the ...
Análise da qualidade do ar : um estudo de séries temporais para dados de contagem
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2013-04-30)
The aim of this study was to investigate the monthly amount of unfavourable days to pollutant dispersion in the atmosphere on the metropolitan region of S ão Paulo (RMSP). It was considered two data sets derived from the ...
Multivariate analysis and vigor tests to determine the quality of Brachiaria decumbens seeds
(Univ Federal Ceara, Dept Geol, 2019-04-01)
This study aimed to verify the efficiency of multivariate analysis in the identification of promising vigor tests for the evaluation of the physiological quality of seed lots of Brachiaria decumbens cv. Basilisk. Seeds of ...
