Assessing the significance of covariates in output oriented data envelopment analysis with two stage regression models. 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... ... Repositório: BDPA Ano de publicação: 2014
Stability and adaptability of runner peanut genotypes based on nonlinear regression and AMMI analysis. The objective of this work was to estimate the stability and adaptability of pod and seed yield in runner peanut genotypes based on the nonlinear regression and AMMI analysis. Yield data from 11 trial... ... Repositório: BDPA Ano de publicação: 2012
Modeling enteric methane emission from beef cattle in Brazil: a proposed equation performed by principal component analysis and mixed modeling multiple regression. Brazil has the largest commercial beef cattle herd in the world but does not have its own model to predict methane (CH4 ) emission. The aim of this study was to create the first empirical enteric CH4... ... Repositório: BDPA Ano de publicação: 2014
Rapid and environmentally friendly wine analysis using Vis/NIR Spectroscopy and Support Vector Machine regression. The aim of this study was to calibrate and validate models that can be used to determine quality parameters in red wine using Vis/NIR spectroscopy and the Least Squares Support Vector Machine (LS-SVM)... ...

A comparison of regression methods based on dimensional reduction for genomic prediction. 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... ... Repositório: BDPA Ano de publicação: 2021
Management of agricultural research center in Brazil: a DEA application using a dynamic GMM approach. In this paper, we measure the performance for each of the Brazilian Agricultural Research Corporation research center by means of a Data Envelopment Analysis model. Performance data are available for... ... Repositório: BDPA Ano de publicação: 2015
Distribution of goat breeds in brazil and their relationship with environmental controls. Abstract: The localization of all flocks of purebred goats in Brazil was spatialized in ARCGIS along with climatic (THI, precipitation, topography, relative humidity) and physical environmental contro... ...
