Metodologia baseada em técnicas de mineração de dados para suporte à certificação de raças de ovinos. Author(s): VIEIRA, F. D.; OLIVEIRA, S. R. de M.; PAIVA, S. R. O objetivo deste trabalho foi desenvolver uma metodologia baseada em técnicas de mineração de dados para selecionar os principais marcadores SNP (Single Nucleotide Polymorphism) para as raças de ovino... ... Repository: BDPA Publication year: 2015
A comparison of regression methods based on dimensional reduction for genomic prediction. Author(s): COSTA, J. A. da; AZEVEDO, C. F.; NASCIMENTO, M.; SILVA, F. F. e; RESENDE, M. D. V. de; NASCIMENTO, A. C. C. multicollinearity and high dimensionality problems, making it impossible to obtain stable estimates through the traditional method of estimation based on ordinary least squares. To overcome such chall... ... Repository: BDPA Publication year: 2021
A non-archimedean dea model to assess group comparisons. Author(s): SOUZA, G. da S. e; GOMES, E. G. We consider the use of the non-Archimedean infinitesimal epsilon in DEA-CCR models. The application of interest is defined by the performance measure of the Brazilian Agricultural Research Corporation... ... Repository: BDPA Publication year: 2016
Simulation of robust adaptive regression multi-level models for quality analysis of special coffees in cold storage. Author(s): MANOEL, I. dos S.; RESENDE, M.; SOUSA, P. H. A.; ROSA, S. D. V. F. da; CIRILLO, M. A. ABSTRACT. Numerous factors contribute to specialty coffee quality, storage and cooling conditions. We may therefore assume that sensory evaluation results can be corrupted by measurement errors, espec... ... Repository: BDPA Publication year: 2024
Cluster analysis of breeding values for milk yield and lactation persistency in Guzerá cattle. Author(s): CRUZ, D. A. C. da; SAVEGNAGO, R. P.; SANTANA, A. B. B.; PEIXOTO, M. G. C. D.; BRUNELI, F. A. T.; FARO, L. El ABSTRACT - The aim of this study was to explore the pattern of genetic lactation curves of Guzerá cattle using cluster analysis. Test-day milk yields of 5,274 first-lactation Guzerá cows were recorded... ... Repository: BDPA Publication year: 2016
Assessing the determinants of rural income dispersion in Brazil. Author(s): SOUZA, G. da S. e; GOMES, E. G.; ALVES, E. R. de A. This article has as its objective the analysis of rural income dispersion in Brazil. To this en we fit econometric regression models using the Gini index as the dependent variable, tecnology, and envi... ... Repository: BDPA Publication year: 2015
Lumber volume modeling of Amazon Brazilian species. Author(s): LIMA. R. B. de; FERREIRA, R. L. C.; SILVA, J. A. A. da; GUEDES, M. C.; OLIVEIRA, C. P. de; SILVA, D. A. S. da; SANTOS, R. M.; CARVALHO, E. P. F.; SILVA, R. M. de A. Accurate estimates of lumber volume become an important indicator of production and monetary value for a sawmill. However, such estimates are only obtained directly after logging, and no accurate pred... ... Repository: BDPA Publication year: 2019
Water stress in modern upland rice cultivars: a multivariate study between physiological traits and yield. Author(s): QUILOANGO-CHIMARRO, C. A.; COELHO, R. D.; COSTA, J. de O.; GUNDIM, A. da S.; HEINEMANN, A. B. Water stress negatively affects upland rice production. The objective of this study was to identify physiological traits that could depict yield responses under water stress conditions. Three modern u... ... Repository: BDPA Publication year: 2023
Modelos empíricos para estimar o acúmulo de matéria seca de capim-marandu com variáveis agrometeorológicas. Author(s): CRUZ, P. G.; SANTOS, P. M.; PEZZOPANE, J. R. M.; OLIVEIRA, P. P. A.; ARAUJO, L.
