Regresión y análisis factoriales

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2009
Some recent developments in factor analysis of multi-sets are introduced in this short course. The more usual factor analyses are based on the singular values de-composition.

Estimación no paramétrica de la densidad y de la regresión - previsión no paramétrica

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2009
We begin with a short wiew of non parametric estimation of density and regression; then we give details and interpretation of a forecasting method, called non parametric forecasting .

On the Number of Balanced Words of Given Length and Height over a Two-Letter Alphabet [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2010
We exhibit a recurrence on the number of discrete line segments joining two integer points in the plane using an encoding of such segments as balanced words of given length and height over the two-letter alphabet $\{0,1\}$.

Assessing the risk of cascading COVID-19 outbreaks from prison-to-prison transfers

open access: yesEpidemics, 2021
COVID-19 transmission has been widespread across the California prison system, and at least two of these outbreaks were caused by transfer of infected individuals between prisons.

Composite Tests under Corrupted Data

open access: yesEntropy, 2019
This paper focuses on test procedures under corrupted data. We assume that the observations Z i are mismeasured, due to the presence of measurement errors. Thus, instead of Z i for i = 1 , … , n, we observe X i = Z i +

Introduction to vector quantization and its applications for numerics*

open access: yesESAIM: Proceedings and Surveys, 2015
We present an introductory survey to optimal vector quantization and its first applications to Numerical Probability and, to a lesser extent to Information Theory and Data Mining. Both theoretical results on the quantization rate of a

Jackknife bias‐corrected variance estimation for the generalized regression estimator

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Commonly used variance estimators for the generalized regression estimator (GREG) are based on Taylor linearization and jackknife. Traditionally, a jackknife GREG variance estimator is obtained by jackknifing GREG, which consists of computing GREG from each of several subsamples of the parent sample, and estimating the variance of the parent ...

Urban wild meat and pangolin consumption across southern forested Cameroon: The limited influence of COVID‐19

open access: yesPeople and Nature, EarlyView.
Abstract Overexploitation of wildlife is pervasive in many tropical regions, and in addition to being a significant conservation and sustainability concern, it has received global attention given discussions over the origins of zoonotic disease outbreaks.

Reporting Control Deficiencies in Repeat Internal Audit Engagements*

open access: yesAccounting Perspectives, Volume 24, Issue 1, Page 7-20, March 2025.
ABSTRACT This study examines the reporting of control deficiencies in repeat internal audit engagements. Experienced internal auditors were presented with a hypothetical case in which they were asked about the likelihood of reporting an internal control deficiency discovered last year but which was, “through an oversight,” not reported to company ...
