Modeling Skewness in Human Transcriptomes / Casellas Vidal, Joaquim (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Varona, Luis (Universidad de Zaragoza. Departamento de Anatomía, Embriología y Genética Animal)
Gene expression data are influenced by multiple biological and technological factors leading to a wide range of dispersion scenarios, although skewed patterns are not commonly addressed in microarray analyses. [...]

A new class of Skew-Normal-Cauchy Distribution / Arrué, Jaime (Universidad de Antofagasta (Antofagasta, Xile). Departamento de Matemáticas) ; Gómez, Héctor W. (Universidad de Antofagasta (Antofagasta, Xile). Departamento de Matemáticas) ; Salinas, Hugo S. (Universidad de Atacama (Copiapo, Xile). Departamento de Matemáticas) ; Bolfarine, Heleno (Universidade de São Paulo. Departamento de Estadística)
In this paper we study a new class of skew-Cauchy distributions inspired on the family extended two-piece skew normal distribution. The new family of distributions encompasses three well known families of distributions, the normal, the two-piece skew-normal and the skew-normal-Cauchy distributions. [...]

A note on the Fisher information matrix for the skew-generalized-normal model / Arellano-Valle, Reinaldo B. (Pontificia Universidad Católica de Chile. Departamento de Estadística) ; Gómez, Héctor W. (Universidad de Antofagasta (Chile). Departamento de Matemáticas) ; Salinas, Hugo S. (Universidad de Atacama (Chile). Departamento de Matemática)
In this paper, the exact form of the Fisher information matrix for the skew-generalized normal (SGN) distribution is determined. The existence of singularity problems of this matrix for the skewnormal and normal particular cases is investigated. [...]

Optimal inverse Beta(3,3) transformation in kernel density estimation / Bolancé, Catalina
A double transformation kernel density estimator that is suitable for heavy-tailed distributions is presented. Using a double transformation, an asymptotically optimal bandwidth parameter can be calculated when minimizing the expression of the asymptotic mean integrated squared error of the transformed variable. [...]

The Asymmetry of IBEX-35 Returns With TAR Models / Márquez Cebrián, Ma. Dolores ; Villazón Hervás, César ; Universitat Autònoma de Barcelona. Departament d'Economia de l'Empresa
It is a general belief in the market that the behaviour of stock prices in a bull market is different from that in a bear market; the magnitude of returns could be different when the return is positive or when it is negative. [...]
