Statistical analysis of texture in trunk images for biometric identification of tree species
(Springer, 2015-04-01)
The identification of tree species is a key step for sustainable management plans of forest resources, as well as for several other applications that are based on such surveys. However, the present available techniques are ...
X̄ Charts with Variable Parameters
(1999-10-01)
Varying the parameters of the X̄ chart has been explored extensively in recent years. In this paper, we extend the study of the X̄ chart with variable parameters to include variable action limits. The action limits establish ...
AATS for the X̄ Chart with Variable Parameters
(1999-10-01)
A Fortran computer program is given for the computation of the adjusted average time to signal, or AATS, for adaptive X̄ charts with one, two, or all three design parameters variable: the sample size, n, the sampling ...
Hubble parameter reconstruction from a principal component analysis: minimizing the bias
(EDP SCIENCES S A, 2011)
Aims. A model-independent reconstruction of the cosmic expansion rate is essential to a robust analysis of cosmological observations. Our goal is to demonstrate that current data are able to provide reasonable constraints ...
Fractional statistics description applied to protein adsorption: effects of excluded surface area on adsorption equilibria
(Elsevier, 2013-08)
Adsorption of large molecules blocking more than one adsorption center on a lattice is described as a fractional statistics problem, based on Haldane’s statistics. Excluded surface area is characterized by a statistical ...
Double-objective economic statistical design of the VP T-2 control chart: Wald's identity approach
(Taylor & Francis Ltd, 2014-10-01)
Research has shown that applying the T-2 control chart by using a variable parameters (VP) scheme yields rapid detection of out-of-control states. In this paper, the problem of economic statistical design of the VP T-2 ...
Nakagami-m Phase-Envelope Joint Distribution: A New Model
(Ieee-inst Electrical Electronics Engineers IncPiscatawayEUA, 2010)
Reduction of Models in the Presence of Nuisance Parameters
(UNIV NAC COLOMBIA, DEPT ESTADISTICA, 2009)
In many statistical inference problems, there is interest in estimation of only some elements of the parameter vector that defines the adopted model. In general, such elements are associated to measures of location and the ...
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 ...
Kinematic constraints on spatial curvature from supernovae Ia and cosmic chronometers
(2021-01-01)
An approach to estimate the spatial curvature ωk from data independently of dynamical models is suggested, through kinematic parametrizations of the comoving distance [DC(z)] with third-degree polynomial, of the Hubble ...
