    • A new class of Skew-Normal-Cauchy Distribution 

      Arrué, Jaime; Gómez, Héctor W.; Salinas, Hugo S.; Bolfarine, Heleno (Institut d'Estadística de Catalunya, 2015-06)
      Article
      Open Access
      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, ...
    • A note on the Fisher information matrix for the skew-generalized-normal model 

      Arellano-Valle, Reinaldo B.; Gómez, Héctor W.; Salinas, Hugo S. (Institut d'Estadística de Catalunya, 2013)
      Article
      Open Access
      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 skew-normal and normal particular ...
    • An extension of the slash-elliptical distribution 

      Rojas, Mario A.; Bolfarine, Heleno; Gómez, Héctor W. (Institut d'Estadística de Catalunya, 2014-12-04)
      Article
      Open Access
      This paper introduces an extension of the slash-elliptical distribution. This new distribution is generated as the quotient between two independent random variables, one from the elliptical family (numerator) and the other ...
    • Likelihood-based inference for the power regression model 

      Martínez-Flórez, Guillermo; Bolfarine, Heleno; Gómez, Héctor W. (Institut d'Estadística de Catalunya, 2015-12)
      Article
      Open Access
      In this paper we investigate an extension of the power-normal model, called the alpha-power model and specialize it to linear and nonlinear regression models, with and without correlated errors. Maximum likelihood estimation ...
    • The Pareto IV power series cure rate model with applications 

      Gallardo, Diego I.; Gómez, Yolanda M.; Arnold, Barry C.; Gómez, Héctor W. (Institut d'Estadística de Catalunya, 2017-12-19)
