Modelo destrutivo com variável terminal em experimentos quimiopreventivos de tumores em animais
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Estatística, 2012-04-12)
The chemical induction of carcinogens in chemopreventive animal experiments is becoming increasingly frequent in biological research. The purpose of these biological experiments is to evaluate the effect of a particular ...
Classe de distribuições série de potências inflacionadas com aplicações
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Estatística, 2009-04-06)
This work has as central theme the Inflated Modified Power Series Distributions, where the objective is to study its main properties and the applicability in the bayesian context. This class of models includes the generalized ...
Estimation and influence diagnostics for zero-inflated hyper-Poisson regression model: full Bayesian analysis
(Taylor & Francis Inc, 2018-01-01)
The purpose of this paper is to develop a Bayesian analysis for the zero-inflated hyper-Poisson model. Markov chain Monte Carlo methods are used to develop a Bayesian procedure for the model and the Bayes estimators are ...
The zero-inflated Conway-Maxwell-Poisson distribution: Bayesian inference, regression modeling and influence diagnostic
(Elsevier B.V., 2014-11-01)
In this paper we propose the zero-inflated COM-Poisson distribution. We develop a Bayesian analysis for our model via on Markov chain Monte Carlo methods. We discuss regression modeling and model selection, as well as, ...
On estimation and influence diagnostics for zero-inflated negative binomial regression models
(ELSEVIER SCIENCE BV, 2011)
The zero-inflated negative binomial model is used to account for overdispersion detected in data that are initially analyzed under the zero-Inflated Poisson model A frequentist analysis a jackknife estimator and a ...
Multivariate models for correlated count data
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 ...
Modelos inflacionados de zeros: aplicações na análise de um questionário de frequencia alimentar
This study aimed at using zero-inflated models to analyze a food frequency questionnaire (F.F.Q.) applied to elderly individuals from a medium-sized city in inner São P aulo state, investigating the models that can be best ...
Predictive ability of alternative models for genetic analysis of clinical mastitis
