13 p, 2.1 MB Population genetic analysis of bi-allelic structural variants from low-coverage sequence data with an expectation-maximization algorithm / Lucas Lledó, José Ignacio (Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB)) ; Vicente Salvador, David (Universitat Autònoma de Barcelona. Institut de Biotecnologia i de Biomedicina "Vicent Villar Palasí") ; Aguado, Cristina (Universitat Autònoma de Barcelona. Institut de Biotecnologia i de Biomedicina "Vicent Villar Palasí") ; Cáceres Aguilar, Mario (Institució Catalana de Recerca i Estudis Avançats)
Population genetics and association studies usually rely on a set of known variable sites that are then genotyped in subsequent samples, because it is easier to genotype than to discover the variation. [...]

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. [...]

24 p, 1.2 MB Point and interval estimation for the logistic distribution based on record data / Asgharzadeh, Akbar (University of Mazandaran (Babolsar, Iran). Department of Statistics) ; Valiollahi, Reza (Semnan University (Iran). Department of Mathematics, Statistics and Computer Science) ; Abdi, Mousa (Higher Education Complex of Bam. Department of Mathematics and Soft Computing)
In this paper, based on record data from the two-parameter logistic distribution, the maximum likelihood and Bayes estimators for the two unknown parameters are derived. The maximum likelihood estimators and Bayes estimators can not be obtained in explicit forms. [...]

22 p, 237.6 KB Likelihood-based inference for the power regression model / Martínez-Flórez, Guillermo (Universidad de Córdoba. Departamento de Matemáticas) ; Bolfarine, Heleno (Universidade de São Paulo. Departamento de Estadística) ; Gómez, Héctor W. (Universidad de Antofagasta (Antofagasta, Xile). Departamento de Matemáticas)
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 is considered with explicit derivation of the observed and expected Fisher information matrices. [...]

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. [...]

14 p, 403.0 KB Hurdle negative binomial regression model with right censored count data / Ehsan Saffari, Seyed (Universiti Teknologi Malaysia. Department of Mathematics, Faculty of Science) ; Adnan, Robiah (Universiti Teknologi Malaysia. Department of Mathematics, Faculty of Science) ; Greene, William (New York University. Department of Economics, Stern School of Business)
A Poisson model typically is assumed for count data. In many cases because of many zeros in the response variable, the mean is not equal to the variance value of the dependent variable. Therefore, the Poisson model is no longer suitable for this kind of data. [...]

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. [...]
