A new class of Skew-Normal-Cauchy Distribution Arrué, Jaime Gómez, Héctor W. Salinas, Hugo S. Bolfarine, Heleno Cauchy distribution Kurtosis Maximum likelihood estimation Singular information matrix Skewness Skew-normal-cauchy distribution 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. Some properties of the new distribution are investigated, inference via maximum likelihood estimation is implemented and results of a real data application, which reveal good performance of the new model, are reported 2015 Article https://ddd.uab.cat/record/132926 urn:oai:ddd.uab.cat:132926 urn:oai:raco.cat:article/294365 urn:articleid:20138830v39n1p35 eng ; SORT : statistics and operations research transactions ; Vol. 39 Núm. 1 (January-June 2015), p. 35-50 open access Aquest document està subjecte a una llicència d'ús Creative Commons.
