16 p, 308.4 KB 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. [...]

10 p, 158.9 KB 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. [...]
