Assessing the significance of covariates in output oriented data envelopment analysis with two stage regression models. Author(s): SOUZA, G. da S. e; GOMES, E. G. We propose alternative regression models to assess the effects of covariates in output oriented DEA scores. We use probability choice models combined with specifications related to the gamma and to th... ... Repository: BDPA Publication year: 2014
Genotype-by-environment interaction and yield stability analysis of biomass sorghum hybrids using factor analytic models and environmental covariates. Author(s): OLIVEIRA, I. C. M.; GUILHEN, J. H. S.; RIBEIRO, P. C. de O.; GEZAN, S. A.; SCHAFFERT, R. E.; SIMEONE, M. L. F.; DAMASCENO, C. M. B.; CARNEIRO, J. E. de S.; CARNEIRO, P. C. S.; PARRELLA, R. A. da C.; PASTINA, M. M. Biomass sorghum has emerged as an alternative crop for biofuel and bioelectricity production. Fresh biomassyield (FBY) is a quantitative trait highly correlated with the calorific power of energy sorg... ... Repository: BDPA Publication year: 2020
Efeito da inclusão da covariância direta-materna no modelo para estimar parâmetros genéticos para peso ao nascimento em ovinos da raça Morada Nova. Author(s): MARTINS JUNIOR, C. T.; ALVES, A. A. C.; PORCÚNCULA, J. A. da; SOUSA, D. R. de; LOBO, R. N. B.; SHIOTSUKI, L. Resumo: Foram utilizados 2916 registros de nascimentos de cordeiros da raça Morada Nova, com o objetivo de avaliar o efeito da inclusão da covariância aditiva-materna na estimativa de parâmetros genét... ...

Factors affecting the performance of Pantaneiro horses. Author(s): SOUZA, G. da S. e; GOMES, E. G.; SANTOS, S. A.; REZENDE, A. S. C. de; ANDRADE, D. R. de F.; NOGUEIRA, M. F.; TRIGO, P.; ABREU, U. G. P. de This study aimed to assess the physical performance of Pantaneiro horses with and without equine infectious anemia (EIA) under functional conditions of cattle management. The horses were subjected to... ... Repository: BDPA Publication year: 2018
Two-stage inference in experimental design using DEA: an application to intercropping and evidence from randomization theory. Author(s): GOMES, E. G.; SOUZA, G. da S. e; VIVALDI, L. J. In this article we propose the use of Data Envelopment Analysis (DEA) measures of efficiency, under constant returns to scale and input equal to unity, in the analysis of multidimensional nonnegative... ...

Repeatability and genetic dissimilarity using biometric traits of black wattle seeds. Author(s): FLÔRES JUNIOR, P. C.; IKEDA, A. C.; SCHUHLI, G. S. e; SILVA, L. D.; HIGA, A. R. Selecting superior individuals requires a careful genetic evaluation. For this reason, repeated measurements of biometric traits need to be carried out in the same individual. This index is a strategi... ... Repository: BDPA Publication year: 2018
Análise de dados de medidas repetidas por meio do modelo linear geral e do modelo misto. Author(s): FREITAS, A. R.; FERREIRA, R. de P.; MOREIRA, A. O delineamento em blocos casualizados com parcelas divididas (split-plot) é um dos mais utilizados na agricultura. São muito comuns situações em que medidas repetidas avaliadas na parcela ao longo do... ... Repository: BDPA Publication year: 2011
Soil evaluation and socioeconomic factors influence on agricultural efficiency: a pilot study in Rio de Janeiro. Author(s): GOMES, E. G.; FIDALGO, E. C. C.; OLIVEIRA, E.; MARTINS, A. L. da S.; OLIVEIRA, A. P. de; COELHO, M. R. In this paper we evaluate the agricultural efficiency of the municipalities of the state Rio de Janeiro and assess the influence of contextual variables on the performance. The scores are computed by... ... Repository: BDPA Publication year: 2022
Analysis of expressed sequence tags from Musa acuminata ssp. burmannicoides, var. Calcutta 4 (AA) leaves submitted to temperature stresses. Author(s): SANTOS, C. M.; MARTINS, N. F.; HORBERG, H. M.; ALMEIDA, E. R. de; COELHO, M. C.; ROGAWA, R. C.; SILVA, F. R. da; MILLER, R. N.; SOUZA JUNIOR, M. T. In order to discover genes expressed in leaves of Musa acuminata ssp. burmannicoides var.
