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 ...

Breeding value accuracy estimates for growth traits using random regression and multi-trait models in Nelore cattle
We quantified the potential increase in accuracy of expected breeding value for weights of Nelore cattle, from birth to mature age, using multi-trait and random regression models on Legendre polynomials and B-spline ...
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 ...
The van Hemmen model and effect of random crystalline anisotropy field
(Elsevier B.V., 2016-01-15)
In this work, we have presented the generalized phase diagrams of the van Hemmen model for spin S=1 in the presence of an anisotropic term of random crystalline field. In order to study the critical behavior of the phase ...
Random regression analyses using B-splines functions to model growth from birth to adult age in Canchim cattle
P>The objective of this work was to estimate covariance functions using random regression models on B-splines functions of animal age, for weights from birth to adult age in Canchim cattle. Data comprised 49 011 records ...
