Using the Sinkhorn divergence in permutation tests for the multivariate two-sample problem

E. del Barrio, J. S. Osorio, A. J. Quiroz

In order to adapt the Wasserstein distance to the large sample multivariate non-parametric two-sample problem, making its application computationally feasible, permutation tests ba…

Regression by clustering using Metropolis-Hastings

Adolfo Quiroz, Simón Ramírez-Amaya, Álvaro Riascos

High quality risk adjustment in health insurance markets weakens insurer incentives to engage in inefficient behavior to attract lower-cost enrollees. We propose a novel methodolog…

A bagging and importance sampling approach to Support Vector Machines

R. Bárcenas, M. D. Gónzalez--Lima, A. J. Quiroz

An importance sampling and bagging approach to solving the support vector machine (SVM) problem in the context of large databases is presented and evaluated. Our algorithm builds o…

Local angles and dimension estimation from data on manifolds

Mateo Díaz, Adolfo J. Quiroz, Mauricio Velasco

For data living in a manifold and a point we consider a statistic which estimates the variance of the angle between pairs of vectors $X…

Machine learning techniques to select Be star candidates. An application in the OGLE-IV Gaia south ecliptic pole field

M. F. Pérez-Ortiz, A. García-Varela, A. J. Quiroz +2

Statistical pattern recognition methods have provided competitive solutions for variable star classification at a relatively low computational cost. In order to perform supervised…

Permutation tests in the two-sample problem for functional data

Alejandra Cabaña, Ana Maria Estrada, Jairo I. Peña +1

Three different permutation test schemes are discussed and compared in the context of the two-sample problem for functional data. One of the procedures was essentially introduced b…
