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
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.

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
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
