Discrete generalized half-normal distribution and its applications in quantile regression / Gallardo, Diego (Universidad de Atacama, Copiapó (Xile). Departamento de Matemática) ; Gómez-Déniz, Emilio (Universidad de Las Palmas de Gran Canaria. Departamento de Métodos Cuantitativos en Economía y Gestión) ; Gómez, Héctor W. (Universidad de Antofagasta (Xile). Departamento de Matemáticas)
A new discrete two-parameter distribution is introduced by discretizing a generalized half-normal distribution. The model is useful for fitting overdispersed as well as underdispersed data. The failure function can be decreasing, bathtub shaped or increasing. [...]

A probabilistic model for explaining the points achieved by a team in football competition : forecasting and regression with applications to the Spanish competition / Gómez-Déniz, Emilio (Universidad de Las Palmas de Gran Canaria) ; Dávila Cárdenes, Nancy (Universidad de Las Palmas de Gran Canaria) ; Pérez Sánchez, José María (Universidad de Las Palmas de Gran Canaria)
In the last decades, a lot of research papers applying statistical methods for analysing sports data have been published. Football, also called soccer, is one of the most popular sports all over the world organised in national championships in a round robin format in which the team reaching the most points at the end of the tournament wins the competition. [...]

A bivariate response model for studying the marks obtained in two jointly-dependent modules in higher education / Gómez-Déniz, Emilio (Universidad de Las Palmas de Gran Canaria. Departamento de Métodos Cuantitativos en Economía y Gestión) ; Dávila Cárdenes, Nancy (Universidad de Las Palmas de Gran Canaria. Departamento de Métodos Cuantitativos en Economía y Gestión) ; García Artiles, María Dolores (Universidad de Las Palmas de Gran Canaria. Departamento de Métodos Cuantitativos en Economía y Gestión)
We study the factors which may affect students' marks in two modules, mathematics and statistics, taught consecutively in the first year of a Business Administration Studies degree course. For this purpose, we introduce a suitable bivariate regression model in which the dependent variables have bounded support and the marginal means are functions of explanatory variables. [...]

Construction of multivariate distributions : a review of some recent results / Sarabia, José María (Universidad de Cantabria. Departamento de Economía) ; Gómez-Déniz, Emilio (Universidad de Las Palmas de Gran Canaria)
The construction of multivariate distributions is an active field of research in theoretical and applied statistics. In this paper some recent developments in this field are reviewed. Specifically, we study and review the following set of methods: (a) Construction of multivariate distributions based on order statistics, (b) Methods based on mixtures, (c) Conditionally specified distributions, (d) Multivariate skew distributions, (e) Distributions based on the method of the variables in common and (f) Other methods, which include multivariate weighted distributions, vines and multivariate Zipf distributions.
