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 ...
A modified runs test for symmetry
(2012-01-05)
We propose a modification of a Modarres–Gastwirth test for the hypothesis of symmetry about a known
center. By means of a Monte Carlo Study we show that the modified test overtakes the original Modarres–
Gastwirth test ...
Local power properties of some asymptotic tests in symmetric linear regression models
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In this paper we obtain asymptotic expansions, up to order n(-1/2) and under a sequence of Pitman alternatives, for the nonnull distribution functions of the likelihood ratio, Wald, score and gradient test statistics in ...
Statistical analysis of proficiency testing results under elliptical distributions
(ELSEVIER SCIENCE BV, 2009)
The use of inter-laboratory test comparisons to determine the performance of individual laboratories for specific tests (or for calibration) [ISO/IEC Guide 43-1, 1997. Proficiency testing by interlaboratory comparisons - ...
Homogeneity tests among groups for microsatellite data
(Taylor & Francis LtdAbingdonInglaterra, 2011)
A practitioner’s guide to developing critical appraisal skills What is the difference between clinical and statistical significance?
(American Dental Association, 2013)
Background. It is common to find published studies in
which the authors claim to have found significant results.
However, many times these results are only statistically
significant with no meaningful impact in clinical ...

True versus apparent Malaria infection prevalence: The contribution of a Bayesian approach
(Public Library of Science, 2011)
Aims: To present a new approach for estimating the "true prevalence" of malaria and apply it to datasets from Peru, Vietnam, and Cambodia. Methods: Bayesian models were developed for estimating both the malaria prevalence ...
