  • The relevance of multi-country input-output tables in measuring emissions trade balance of countries: the case of Spain 

    Sanz, Teresa; Yñiguez, Rocío; Rueda-Cantuche, José Manuel (Institut d'Estadística de Catalunya, 2016-06-17)
    Article
    Accés obert
    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 ...
  • Two alternative estimation procedures for the negative binomial cure rate model with a latent activation scheme 

    Gallardo, Diego I.; Bolfarine, Heleno (Institut d'Estadística de Catalunya, 2016-06-17)
    Article
    Accés obert
    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 ...
  • A test for normality based on the empirical distribution function 

    Torabi, Hamzeh; Montazeri, Narges H.; Grané, Aurea (Institut d'Estadística de Catalunya, 2016-06-17)
    Article
    Accés obert
    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 ...
  • Point and interval estimation for the logistic distribution based on record data 

    Asgharzadeh, Akbar; Valiollahi, Reza; Abdi, Mousa (Institut d'Estadística de Catalunya, 2016-06-17)
    Article
    Accés obert
    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 ...
  • A goodness-of-fit test for the multivariate Poisson distribution 

    Novoa-Muñoz, Francisco; Jiménez-Gamero, María Dolores (Institut d'Estadística de Catalunya, 2016-06-17)
    Article
    Accés obert
    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 ...
  • Exploring Bayesian models to evaluate control procedures for plant disease 

    Alvares, Danilo; Armero, Carmen; Forte, Anabel; Rubio, Luis (Institut d'Estadística de Catalunya, 2016-06-17)
    Article
    Accés obert
    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 ...
  • Transmuted geometric distribution with applications in modeling and regression analysis of count data 

    Chakraborty, Subrata; Bhati, Deepesh (Institut d'Estadística de Catalunya, 2016-06-17)
    Article
    Accés obert
    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 ...
  • Compound distributions motivated by linear failure rate 

    Gitifar, Narjes; Rezaei, Sadegh; Nadarajah, Saralees (Institut d'Estadística de Catalunya, 2016-06-17)
    Article
    Accés obert
    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 ...
  • A statistical learning based approach for parameter fine-tuning of metaheuristics 

    Calvet, Laura; Juan, Angel A.; Serrat, Carles; Ries, Jana (Institut d'Estadística de Catalunya, 2016-06-17)
    Article
    Accés obert
    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 ...
