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 ...
Bootstrap validity for the score test when instruments may be weak
(2009)
It is well-known that size adjustments based on bootstrapping the t-statistic perform poorly when instruments are weakly correlated with the endogenous explanatory variable. In this paper, we provide a theoretical proof ...
