Predictive ability of alternative models for genetic analysis of clinical mastitis
Anaerobic threshold estimation by statistical modelling.
Anaerobic threshold (AT) is usually estimated as a change point problem by visual analysis of the cardiorespiratory response to incremental dynamic exercise. In this study, two phase linear (TPL) models of the linear-linear ...
Threshold selection for extremes under a semiparametric model
(Springer Heidelberg, 2013-07)
In this work we propose a semiparametric likelihood procedure for the threshold selection for extreme values.This is achieved under a semiparametric model,which assumes there is a threshold above which the excess distribution ...
A general threshold stress hybrid hazard model for lifetime data
(SPRINGERNEW YORK, 2012)
In this paper we propose a hybrid hazard regression model with threshold stress which includes the proportional hazards and the accelerated failure time models as particular cases. To express the behavior of lifetimes the ...
Bayesian analysis of extreme events with threshold estimation
(Fundação Getulio Vargas. Escola de Pós-graduação em Economia, 2004-08-20)
The aim of this paper is to analyze extremal events using Generalized Pareto Distributions (GPD), considering explicitly the uncertainty about the threshold. Current practice empirically determines this quantity and proceeds ...
An assessor-specific Bayesian multi-threshold mixed model for analyzing ordered categorical traits in tree breeding
(Springer Heidelberg, 2013-12)
Many traits of biological interest in tree breeding are assessed using more than two ordered discrete categories. These scores have a more or less arbitrary and subjective assignment by the assessors, which could lead to ...
Testing linearity against threshold effects: uniform inference in quantile regression
(Springer Heidelberg, 2014-04)
This paper develops a uniform test of linearity against threshold effects in the quantile regression framework. The test is based on the supremum of the Wald process over the space of quantile and threshold parameters. We ...
Two versions of the threshold contact model in two dimensions
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Two versions of the threshold contact process ordinary and conservative - are studied on a square lattice. In the first, particles are created on active sites, those having at least two nearest neighbor sites occupied, and ...
Directly transmitted infections modeling considering an age-structured contact rate - Epidemiological analysis
