Quantifying individual variation in reaction norms using random regression models fitted through Legendre polynomials: application in eucalyptus breeding. Author(s): ALVES, R. S.; RESENDE, M. D. V. de; ROCHA, J. R. do A. S. de C.; PEIXOTO, M. A.; TEODORO, P. E.; SILVA, F. F. e; BHERING, L. L.; SANTOS, G. A. dos An accurate, efficient and informative statistical method for analyses of genotype × environment (G × E) interactions is a key requirement for progress in any breeding program. Thus, the objective of... ... Repository: BDPA Publication year: 2020
Covariance functions under B-spline polynomials to model Polled Nellore cattle growth. Author(s): CAVALCANTE, D. H.; LUZ, C. S. M.; OLIVEIRA, M. R. A. de; FONSECA, W. J. L.; EVANGELISTA, A. F.; MARTINS FILHO, R.; MALHADO, C. H. M.; AZEVEDO, D. M. M. R.; SANTOS, K. R. dos; SOUSA JÚNIOR, S, C, de B-spline functions have been used in random regression models (RRM) to model animal weight from birth to adulthood because they are less vulnerable to common difficulties of other methods. However, it... ... Repository: BDPA Publication year: 2021
Efeito materno sobre a curva de crescimento de ovinos Santa Inês por meio de modelos de regressão aleatória. Author(s): SAMENTO, J. L. R.; TORRES, R. de A.; SOUSA, W. H. de; LOBO, R. N. B.; SOUSA, J.

Genetic Parameters for Milk Yield and Lactation Persistency Using Random Regression Models in Girolando Cattle. Author(s): CANAZA-CAYO, A. W.; LOPES, P. S.; SILVA, M. V. G. B.; TORRES, R. de A.; MARTINS, M. F.; ARBEX, W. A.; COBUCI, J. A. Repository: BDPA Publication year: 2015
Estimation of (co)variance components and genetic parameters for weights of red-winged tinamou using random regression models. Author(s): THOLON, P.; QUEIROZ, S. A. The objective of this work was to determine genetic parameters for body weight of tinamou in captivity. It was used random regression models in analyses of data by considering the direct additive gene... ... Repository: BDPA Publication year: 2011
Adjustment of lactation curves of Holstein cows from herds of Minas Gerais, Brazil. Author(s): AZEVEDO JUNIOR, J.; GONÇALVES, T. de M.; SOUZA, J. C. de; RODRIGUEZ, M. A. P.; COSTA, C. N.; CARVALHEIRA, J. G. V. Abstract Random regression models (RRM) differ in terms of the functions used to describe the shape of lactation curves. The aim was to compare random regression models under different functions to de... ... Repository: BDPA Publication year: 2018
Fitting of fixed regression curves with different residual variance structures for Nellore cattle growth modeling. Author(s): CAVALCANTE, D. H.; SOUSA JÚNIOR, S. C.; SILVA, L. P.; MALHADO, C. H. M.; MARTINS FILHO, R.; AZEVEDO, D. M. M. R.; CAMPELO, J. E. G. Different polynomial functions were tested for mean trajectory modeling with different residual variance structures. A total of 15,148 weight records of 3,115 Nellore Mocho cattle with ages between 1... ... Repository: BDPA Publication year: 2020
Genetic parameters for milk production by using random regression models with different alternatives of fixed regression modeling. Author(s): COBUCI, J. A.; COSTA, C. N.; BRACCINI NETO, J.; FREITAS, A. F. de Records of test-day milk yields of the first three lactations of 25,500 Holstein cows were used to estimate genetic parameters for milk yield by using two alternatives of definition of fixed regressio... ...

Genetic parameters for test day milk yields of first lactation Holstein cows by random regression models. Author(s): MELO, C. M. R. de; PACKER, I. U.; COSTA, C. N.; MACHADO, P. F. Covariance components for test day milk yield using 263 390 first lactation records of 32 448 Holstein cows were estimated using random regression animal models by restricted maximum likelihood. Three... ... Repository: BDPA Publication year: 2007
