Maximum covariance analysis to identify intraseasonal oscillations over tropical Brazil
(Springer, 2016-10-21)
Estimates of covariance functions for growth of Nelore cattle applying a parametric correlation structure to model within-animal correlations
(2005-05-01)
A total of 20,065 weights recorded on 3016 Nelore animals were used to estimate covariance functions for growth from birth to 630 days of age, assuming a parametric correlation structure to model within-animal correlations. ...
Minimizing inter-genotypic competition effects to predict genetic values and selection in forestry genetic tests
(Universidade de São Paulo (USP), Escola Superior de Agricultura Luiz de Queiroz (ESALQ), 2011-12-01)
The effect of competition is an important source of variation in breeding experiments. This study aimed to compare the selection of plants of open-pollinated families of Eucalyptus with and without the use of competition ...

Spike-triggered covariance: geometric proof, symmetry properties, and extension beyond Gaussian stimuli
(Springer, 2013-02)
The space of sensory stimuli is complex and high-dimensional. Yet, single neurons in sensory systems are typically affected by only a small subset of the vast space of all possible stimuli. A proper understanding of the ...
Variabilidade espacial e tamanho de parcela em experimentos com culturas olerícolas
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Agronomia, 2013-02-20)
The study aimed to test the efficiency of the method Papadakis on increasing the quality of experiments with snap beans, zucchini, peppers and lettuce, and having efficiency, determine how to estimate the covariate and ...
Cutpoint selection for discretizing a continuous covariate for generalized estimating equations
(ELSEVIER SCIENCE BV, 2011)
We consider consider the problem of dichotomizing a continuous covariate when performing a regression analysis based on a generalized estimation approach. The problem involves estimation of the cutpoint for the covariate ...
