20 p, 278.3 KB A class of goodness-of-fit tests for circular distributions based on trigonometric moments / Rao Jammalamadaka, Sreenivasa (University of California Santa Barbara. Department of Statistics and Applied Probability) ; Jiménez-Gamero, María Dolores (Universidad de Sevilla. Departamento de Estadística e Investigación Operativa) ; Meintanis, Simos G.
We propose a class of goodness-of-fit test procedures for arbitrary parametric families of circular distributions with unknown parameters. The tests make use of the specific form of the characteristic function of the family being tested, and are shown to be consistent. [...]

24 p, 260.6 KB Compound distributions motivated by linear failure rate / Gitifar, Narjes (Amirkabir University of Technology (Teheran, Iran)) ; Rezaei, Sadegh (Amirkabir University of Technology (Teheran, Iran)) ; Nadarajah, Saralees (University of Manchester)
Motivated by three failure data sets (lifetime of patients, failure time of hard drives and failure timeof a product), we introduce three different three-parameter distributions, study basic mathematical properties, address estimation by the method of maximum likelihood and investigate finite sample performance of the estimators. [...]

14 p, 212.2 KB Discrete alpha-skew-Laplace Distribution / Harandi, S. Shams (University of Isfahan. Department of Statistics) ; Alamatsaz, M. H. (University of Isfahan. Department of Statistics)
Classical discrete distributions rarely support modelling data on the set of whole integers. In this paper, we shall introduce a flexible discrete distribution on this set, which can, in addition, cover bimodal as well as unimodal data sets. [...]

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. [...]

20 p, 656.9 KB Double bounded Kumaraswamy-power series class of distributions / Bidram, Hamid (University of Isfahan (Irán). Department of Statistics) ; Nekoukhou, Vahid (University of Isfahan (Irán). Department of Statistics)
In this paper, we will introduce the new Kumaraswamy-power series class of distributions. This new class is obtained by compounding the Kumaraswamy distribution of Kumaraswamy (1980) and the family of power series 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. [...]

22 p, 208.0 KB Stress-strength reliability of Weibull distribution based on progressively censored samples / Asgharzadeh, Akbar ; Valiollahi, Reza ; Raqab, Mohammad Z.
Based on progressively Type-II censored samples, this paper deals with inference for the stress-strength reliability R = P(Y < X) when X and Y are two independent Weibull distributions with different scale parameters, but having the same shape parameter. [...]

22 p, 1.1 MB Estimation in the Birnbaum-Saunders distribution based on scale-mixture of normals and the EM-algorithm / Balakrishnan, Narayanaswamy ; Leiva, Víctor ; Sanhueza, Antonio ; Vilca, Filidor
Scale mixtures of normal (SMN) distributions are used for modeling symmetric data. Members of this family have appealing properties such as robust estimates, easy number generation, and efficient computation of the ML estimates via the EM-algorithm. [...]
