A bootstrap approach for testing invariance under parameterized group actions: orthogonal reflections and axial symmetry
Alejandro Cholaquidis, Juan Cuesta-Albertos, Ricardo Fraiman +1
Testing whether a multivariate distribution is invariant under an orthogonal transformation is a classical problem when the transformation is fixed in advance. We address a harder…
The complex behaviour of Galton rank order statistic
E. del Barrio, J. A. Cuesta-Albertos, C. Matran
Galton's rank order statistic is one of the oldest statistical tools for two-sample comparisons. It is also a very natural index to measure departures from stochastic dominance. Ye…
On Perfect Classification and Clustering for Gaussian Processes
Juan A. Cuesta-Albertos, Subhajit Dutta
In this paper, we propose a data based transformation for infinite-dimensional Gaussian processes and derive its limit theorem. For a classification problem, this transformation in…
Similarity of samples and trimming
Pedro C. Álvarez-Esteban, Eustasio del Barrio, Juan A. Cuesta-Albertos +1
We say that two probabilities are similar at level if they are contaminated versions (up to an fraction) of the same common probability. We show how this model is related t…
Trimming and likelihood: Robust location and dispersion estimation in the elliptical model
Juan A. Cuesta-Albertos, Carlos Matrán, Agustín Mayo-Iscar
Robust estimators of location and dispersion are often used in the elliptical model to obtain an uncontaminated and highly representative subsample by trimming the data outside an…
