Local influence on the general linear model
(Indian Statistical Institute, 1998)
We study the Local Influence on the General Linear Model with a perturbation scheme in the variance-covariance matrix of the random errors. The comparison of the results obtained and the conditional bias have been used to ...

A test for Gaussianity in Hilbert spaces via theempirical characteristic functional
(Wiley, 2020-04-28)
LetX1,X2,...be independent and identically distributedrandom elements taking values in a separable HilbertspaceH. With applications for functional data in mind,Hmay be regarded as a space of square-integrable func-tions, ...

Optimisation of Aiming Strategies in Solar Tower Power Plants
(AIP, 2018-11-08)
Inclement weather effects have a direct impact on the efficiency of a Solar Power Tower plant and have the potential to damage the receiver by flash heating. An optimised aiming strategy for the heliostat field mitigates ...

Computationally efficient goodness-of-fit tests for the error distribution in nonparametric regression
(Instituto Nacional de Estatística (Portugal), 2018-01)
Several procedures have been proposed for testing goodness-of-fit to the error distribution in nonparametric regression models. The null distribution of the associated test statistics is usually approximated by means of a ...

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 ...

The tree based linear regression model for hierarchical categorical variables
(Elsevier, 2022-05-04)
Many real-life applications consider nominal categorical predictor variables that have a hierarchical structure, e.g. economic activity data in Official Statistics. In this paper, we focus on linear regression models built ...

Dominators for multiple-objective quasiconvex maximization problems
(Springer, 2000-01-06)
In this paper we address the problem of finding a dominator for a multiple-objective maximization problem with quasiconvex functions. The one-dimensional case is discussed in some detail, showing how a Branch-and-Bound ...
