Geodesic Hypothesis Testing for Comparing Location Parameters in Elliptical Populations
(Springer India, 2016-02)
In this paper we study the geometry of the differentiable manifold associated with two samples of symmetric distributions in the real line equipped with the Fisher information as Riemannian metric. Expressions for the ...
On the application of discrete-time Volterra series for the damage detection problem in initially nonlinear systems
(2017-01-01)
Nonlinearities in the dynamical behavior of mechanical systems can degrade the performance of damage detection features based on a linearity assumption. In this article, a discrete Volterra model is used to monitor the ...
Hypothesis testing in an errors-in-variables model with heteroscedastic measurement errors
(JOHN WILEY & SONS LTD, 2008)
In many epidemiological studies it is common to resort to regression models relating incidence of a disease and its risk factors. The main goal of this paper is to consider inference on such models with error-prone ...
TESTING STATISTICAL HYPOTHESIS ON RANDOM TREES AND APPLICATIONS TO THE PROTEIN CLASSIFICATION PROBLEM
(INST MATHEMATICAL STATISTICS, 2009)
Efficient automatic protein classification is of central importance in genomic annotation. As an independent way to check the reliability of the classification, we propose a statistical approach to test if two sets of ...
Robust testing for superiority between two regression curves
(Elsevier Science, 2016-05)
The problem of testing the null hypothesis that the regression functions of two populations are equal versus one-sided alternatives under a general nonparametric homoscedastic regression model is considered. To protect ...
A Note on Distinguishing Random Trees Populations
(Taylor & Francis, 2011-12)
This article addresses the problem of identifying differences between populations of trees. Recently, a sophisticated test was proposed by Busch et al. (2009), the BFFS test, a Kolmogorov type of test that maximizes the ...
The polysurvival model with long-term survivors
(Brazilian Statistical AssociationSão Paulo, 2012)
Long-term survival models have historically been considered for analyzing time-to-event data with long-term survivors fraction. However, situations in which a fraction (1 - p) of systems is subject to failure from independent ...
Data analysis in forest sciences: why do we continue using null hypothesis significance tests?
(Universidad Austral de Chile, Facultad de Ciencias Forestales, 2011)
