28 p, 816.7 KB The relevance of multi-country input-output tables in measuring emissions trade balance of countries : the case of Spain / Sanz Díaz, Teresa (Universidad de Sevilla. Departamento de Análisis Económico y Economía Política) ; Yñiguez, Rocío (Universidad de Sevilla. Departamento de Análisis Económico y Economía Política) ; Rueda-Cantuche, José Manuel (European Commission, Joint Research Centre. Institute for Prospective and Technological Studies)
As part of national accounts, input-output tables are becoming crucial statistical tools to study theeconomic, social and environmental impacts of globalization and international trade. In particular,global input-output tables extend the national dimension to the international dimension by relatingindividual countries' input-output tables among each other, thus providing an opportunity to bal-ance the global economy as a whole.

24 p, 284.7 KB Two alternative estimation procedures for the negative binomial cure rate model with a latent activation scheme / Gallardo, Diego (Universidad de Antofagasta (Chile). Departamento de Matemáticas) ; Bolfarine, Heleno (Universidade de São Paulo. Departamento de Estatística)
In this paper two alternative estimation procedures based on the EM algorithm are proposed forthe flexible negative binomial cure rate model with a latent activation scheme. The Weibull modelas well as the log-normal and gamma distributions are also considered for the time-to-event datafor the non-destroyed cells. [...]

34 p, 293.5 KB A test for normality based on the empirical distribution function / Torabi, Hamzeh (Yazd University (Iran). Statistics Department) ; Montazeri, Narges H. (Yazd University (Iran). Statistics Department) ; Grané, Aurea (Universidad Carlos III de Madrid. Departamento de Estadística)
In this paper, a goodness-of-fit test for normality based on the comparison of the theoretical and empirical distributions is proposed. Critical values are obtained via Monte Carlo for several sample sizes and different significance levels. [...]

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. [...]

26 p, 204.3 KB A goodness-of-fit test for the multivariate Poisson distribution / Novoa-Muñoz, Francisco (Universidad del Bío-Bío (Xile). Departamento de Estadística) ; Jiménez-Gamero, María Dolores (Universidad de Sevilla. Departamento de Estadística e Investigación Operativa)
Bivariate count data arise in several different disciplines and the bivariate Poisson distribution is commonly used to model them. This paper proposes and studies a computationally convenient goodness-of-fit test for this distribution, which is based on an empirical counterpart of a system ofequations. [...]

14 p, 437.5 KB Exploring Bayesian models to evaluate control procedures for plant disease / Alvares, Danilo (Universitat de València) ; Armero, Carmen (Universitat de València) ; Forte, Anabel (Universitat de València) ; Rubio, Luis (Instituto Valenciano de Investigaciones Agrarias)
Tigernut tubers are the main ingredient in the production of orxata in Valencia, a white soft sweet popular drink. In recent years, the appearance of black spots in the skin of tigernuts has led to important economic losses in orxata production because severely diseased tubers must be discarded. [...]

24 p, 1.2 MB Transmuted geometric distribution with applications in modeling and regression analysis of count data / Chakraborty, Subrata (Dibrugarh University (Índia). Department of Statistics) ; Bhati, Deepesh (Central University of Rajasthan (Índia). Department of Statistics)
A two-parameter transmuted geometric distribution is proposed as a new generalization of the geometric distribution by employing the quadratic transmutation techniques of Shaw and Buckley. The additional parameter plays the role of controlling the tail length. [...]

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, 294.5 KB A statistical learning based approach for parameter fine-tuning of metaheuristics / Calvet Liñan, Laura (Universitat Oberta de Catalunya) ; Juan, Ángel A., dir. (Universitat Autònoma de Barcelona. Departament de Telecomunicació i Enginyeria de Sistemes) ; Serrat, Carles (Universitat Politècnica de Catalunya. Departament de Matemàtica Aplicada I) ; Ries, Jana (University of Portsmouth. Portsmouth Business School)
Metaheuristics are approximation methods used to solve combinatorial optimization problems. Their performance usually depends on a set of parameters that need to be adjusted. The selectionof appropriate parameter values causes a loss of efficiency, as it requires time, and advanced analytical and problem-specific skills. [...]
