Robust tests for linear regression models based on τ-estimates
(Elsevier Science, 2016-01)
ANOVA tests are the standard tests to compare nested linear models fitted by least squares. These tests are equivalent to likelihood ratio tests, so they have high power. However, least squares estimators are very vulnerable ...
Robust estimation in partially linear regression models with monotonicity constraints
(Taylor & Francis, 2019-11)
Partially linear models are important tools in statistical modelling, combining the flexibility of non–parametric models and the simple interpretation of linear models. Monotonicity constraints appear naturally in certain ...
Modelling subject-specific childhood growth using linear mixed-effect models with cubic regression splines
(BioMed Central, 2016)
BACKGROUND: Childhood growth is a cornerstone of pediatric research. Statistical models need to consider individual trajectories to adequately describe growth outcomes. Specifically, well-defined longitudinal models are ...
Advocating better habitat use and selection models in bird ecology
(Sociedade Brasileira de Ornitologia, 2018-06)
Studies on habitat use and habitat selection represent a basic aspect of bird ecology, due to its importance in natural history, distribution, response to environmental changes, management and conservation. Basically, a ...
Shortened Version of the Token Test: Normative data for Spanish-speaking pediatric population
(IOS Press, 2017)
OBJECTIVE: To generate normative data for the Shortened Version of the Token Test in Spanish-speaking pediatric populations. METHOD: The sample consisted of 4,373 healthy children from nine countries in Latin America (Chile, ...
Partly linear models on Riemannian manifolds
(Taylor & Francis, 2012-05)
In partly linear models, the dependence of the response y on (xT, t) is modeled through the relationship y = xTβ + g(t) + ε, where ε is independent of (xT, t). We are interested in developing an estimation procedure that ...
A Novel Statistical Analysis of Cnidocysts in Acontiarian Sea Anemones (Cnidaria, Actiniaria) Using Generalized Linear Models with Gamma Errors
(Elsevier Gmbh, 2004-11-08)
Comparative studies on cnidocysts, involving adequate statistical treatment, are very scarce. Classical statistical tests are frequently used assuming normal frequency distributions of capsule lengths, but many distributions ...
EM-based Monte Carlo analysis and yield prediction of microwave circuits using linear-input neural-output space mapping
(IEEE Trans. Microwave Theory Tech.;54, 2006-12)
