A note on influence diagnostics in nonlinear mixed-effects elliptical models
(ELSEVIER SCIENCE BV, 2011)
This paper provides general matrix formulas for computing the score function, the (expected and observed) Fisher information and the A matrices (required for the assessment of local influence) for a quite general model ...
New insights on random regret minimization models
(2015)
This paper develops new methodological insights on Random Regret Minimization (RRM) models. It starts by showing that the classical RRM model is not scale-invariant, and that as a result - the degree of regret minimization ...
Análise de dados longitudinais para variáveis binárias
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2009-03-05)
The objective of this work is to present techniques of regression analysis for longitudinal data when the response variable is binary. Initially, there is a review of generalized linear models, marginal models, transition ...
?Zebrafish as an animal model for food safety research: trends in the animal research?
(Taylor & Francis Inc, 2019-10-02)
Toxicity studies in mammals continue to be the most appropriate model for predicting risk in humans, but they tend to be expensive and time-consuming. In the aftermath of the genetic sequencing of zebrafish (Danio rerio), ...
Association between ambient temperature and COVID-19 infection in 122 cities from China
Background: Coronavirus disease 2019 (COVID-19) has become a severe public health problem globally. Both epidemiological and laboratory studies have shown that ambient temperature could affect the transmission and
survival ...
Leafing patterns and leaf exchange strategies of a cerrado woody community
(2018-05-01)
The deciduousness of tropical trees and communities depend on ecosystems characteristics such as plant species diversity, and strength of the dry season. Based on seven years of phenological observations, we provide the ...
Climate-driven statistical models as effective predictors of local dengue incidence in costa rica: a generalized additive model and random forest approachVariables climáticas como predictores de la incidencia de dengue en Costa Rica: un enfoque de modelo aditivo generalizado y bosques aleatorios
(Universidad de Costa Rica, Centro de Investigación en Matemática Pura y Aplicada (CIMPA), 2019)
Accounting for relatedness and spatial structure to improve plant phenotypic selection in the wild
(Springer, 2020)
Identifying natural selection in wild plant populations is a challenging task, as the reliability of selection coefficients depends, among other factors, on the critical assumption of data independence. While rarely examined, ...
