On sparse ensemble methods: an application to short-term predictions of the evolution of COVID-19
(Elsevier, 2021-04-18)
Since the seminal paper by Bates and Granger in 1969, a vast number of ensemble methods that combine different base regressors to generate a unique one have been proposed in the literature. The so-obtained regressor method ...

A Monte Carlo comparison of three consistent bootstrap procedures
(Taylor & Francis, 2009-04)
Since bootstrap samples are simple random samples with replacement from the original sample, the information content of some bootstrap samples can be very low. To avoid this fact, some authors have proposed several variants ...

A new class of tests for multinormality with i.i.d. and garch data based on the empirical moment generating function
(Springer, 2019-06)
We generalize a recent class of tests for univariate normality that are based on the empirical moment generating function to the multivariate setting, thus obtaining a class of affine invariant, consistent and easy-to-use ...

Aproximación a la distribución de ciertos estadísticos en contrastes sobre modelos de regresión no paramétrica
(2017-06-08)
Este trabajo se desarrolla en el contexto de modelos de regresión no paramétrica con diseño aleatorio para variable respuesta y covariable ambas unidimensionales. El conocimiento de la función de distribución del error ...

Testing normality of a large number of populations
(Springer, 2023-02-12)
This paper studies the problem of simultaneously testing that each of k independent samples come from a normal population. The means and variances of those populations may differ. The proposed procedures are based on the ...

Una generalización de la métrica de Hausdorff sobre C(Rn)
(Universidad Industrial de Santander, 2009)
En este trabajo hacemos una extensión de la métrica de Hausdorff H sobre C(Rn), el espacio de todos los conjuntos difusos cerrados en Rn, obteniendo una familia de métricas Df. Estudiamos algunas propiedades topológicas ...

Testing the equality of a large number of means of functional data
(Elsevier, 2021)
Given k independent samples of functional data, this paper deals with the problem of testing for the equality of their mean functions. In contrast to the classical setting, where k is kept fixed and the sample size from ...

A non-parametric ANOVA-type test for regression curves based on characteristic functions
(Wiley, 2015-03)
This article studies a new procedure to test for the equality of k regression curves in a fully nonparametric context. The test is based on the comparison of empirical estimators of the characteristic functions of the ...

Characterizations of multinormality and corresponding tests of fit, including for Garch models
(Cornell University, 2018-05-22)
We provide novel characterizations of multivariate normality that incorporate both the characteristic function and the moment generating function, and we employ these results to construct a class of affine invariant, ...

The Power Muth Distribution
(Vilnius teach journals, 2017-03-18)
Muth introduced a probability distribution with application in reliability theory. We propose a new model from the Muth law. This paper studies its statistical properties, such as the computation of the moments, computer ...
