Robust tests in generalized linear models with missing responses
(Elsevier Science Bv, 2013-09)
In many situations, data follow a generalized linear model in which the mean of the responses is modelled, through a link function, linearly on the covariates. Robust estimators for the regression parameter in order to ...
Sufficients conditions for analysis of extrema in the step-response of the linear control systems
(Institute of Electrical and Electronics Engineers (IEEE), 2011-12-01)
This note deals whith the problem of extrema which may occur in the step-response of a stable linear system with real zeros and poles. Some simple sufficients conditions and necessary conditions are presented for analyses ...
Algorithms for network piecewise-linear programs: A comparative study
Piecewise-Linear Programming (PLP) is an important area of Mathematical Programming and concerns the minimisation of a convex separable piecewise-linear objective function, subject to linear constraints. In this paper a ...
Robust inference in partially linear models with missing responses
(Elsevier Science, 2014-11)
We consider robust testing on the regression parameter of a partially linear regression model, where missing responses are allowed. We derive the asymptotic behavior of the proposed test statistic under the null and ...
Modelos de predição para sobrevivência de plantas de Eucalyptus grandis
(Editora da Universidade Federal de Lavras, 2009)
Objetivou-se com este trabalho comparar modelos de predição de plantas sobreviventes de Eucalyptus grandis. Utilizaram-se os seguintes modelos: modelo linear misto com os dados transformados, utilizando-se as transformações ...
Fuzzy pole placement based on piecewise Lyapunov functions
(JOHN WILEY & SONS LTD, 2010)
This paper presents a controller design method for fuzzy dynamic systems based on piecewise Lyapunov functions with constraints on the closed-loop pole location. The main idea is to use switched controllers to locate the ...
Characterization of the Earwig, Doru lineare , as a Predator of Larvae of the Fall Armyworm, Spodoptera frugiperda : A Functional Response Study
(University of Arizona, 2010-04)
Spodoptera frugiperda Smith (Lepidoptera: Noctuidae) is considered as the most important pest of maize in almost all tropical America. In Argentina, the earwig Doru lineare Eschscholtz (Dermaptera: Forficulidae) has been ...
Robust inference in generalized partially linear models
(Elsevier Science, 2010-12)
In many situations, data follow a generalized partly linear model in which the mean of the responses is modeled, through a link function, linearly on some covariates and nonparametrically on the remaining ones. A new class ...
Asymptotic behavior of robust estimators in partially linear models with missing responses: The effect of estimating the missing probability on the simplified marginal estimators
In this paper, we consider a semiparametric partially linear regression model where missing data occur in the response. We derive the asymptotic behavior of the robust estimators for the regression parameter and of the ...
Functional response of Sagitta setosa (Chaetognatha) and Mnemiopsis leidyi (Ctenophora) under variable food concentration in the Gullmar fjord, Sweden
