The relevance of multi-country input-output tables in measuring emissions trade balance of countries: the case of Spain
(Institut d'Estadística de Catalunya, 2016-06-17)
Article
Accés obertAs 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 ... -
Two alternative estimation procedures for the negative binomial cure rate model with a latent activation scheme
(Institut d'Estadística de Catalunya, 2016-06-17)
Article
Accés obertIn 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 ... -
A test for normality based on the empirical distribution function
(Institut d'Estadística de Catalunya, 2016-06-17)
Article
Accés obertIn 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 ... -
Point and interval estimation for the logistic distribution based on record data
(Institut d'Estadística de Catalunya, 2016-06-17)
Article
Accés obertIn 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 ... -
A goodness-of-fit test for the multivariate Poisson distribution
(Institut d'Estadística de Catalunya, 2016-06-17)
Article
Accés obertBivariate 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 ... -
Exploring Bayesian models to evaluate control procedures for plant disease
(Institut d'Estadística de Catalunya, 2016-06-17)
Article
Accés obertTigernut 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 ... -
Transmuted geometric distribution with applications in modeling and regression analysis of count data
(Institut d'Estadística de Catalunya, 2016-06-17)
Article
Accés obertA 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 ... -
Compound distributions motivated by linear failure rate
(Institut d'Estadística de Catalunya, 2016-06-17)
Article
Accés obertMotivated 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 ... -
A statistical learning based approach for parameter fine-tuning of metaheuristics
(Institut d'Estadística de Catalunya, 2016-06-17)
Article
Accés obertMetaheuristics 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 ...
