  • Introducing migratory flows in life table construction 

    Pavía, Jose M.; Morillas, Francisco; Lledó, Josep (Institut d'Estadística de Catalunya, 2012)
    Article
    Open Access
    The purpose of life tables is to describe the mortality behav iour of particular groups. The construction of general life tables is based on death statis tics and census figures of resident populations under the ...

  • Decision-making techniques with similarity measures and OWA operators 

    Merigó, José M.; Gil-Lafuente, Anna M. (Institut d'Estadística de Catalunya, 2012)
    Article
    Open Access
    We analyse the use of the ordered weighted average (OWA) in de cision-making giving special attention to business and economic decision-making proble ms. We present several aggregation techniques that are very useful ...

  • Comparing and calibrating discrepancy measures for Bayesian model selection 

    Horra, Julián de la; Rodríguez-Bernal, María Teresa (Institut d'Estadística de Catalunya, 2012)
    Article
    Open Access
    Different approaches have been considered in the literatur e for the problem of Bayesian model selection. Recently, a new method was introduced and analys ed in De la Horra (2008) by minimizing the posterior expected ...

  • A comparison of some confidence intervals for estimating the population coefficient of variation: a simulation study

    Article
    Open Access
    This paper considers several confidence intervals for estim ating the population coefficient of variation based on parametric, nonparametric and modified m ethods. A simulation study has been conducted to compare the ...

  • Analysing visual receptive fields through generalised additive models with interactions 

    Rodríguez Álvarez, María Xosé; Cadarso-Suárez, Carmen; González, Francisco (Institut d'Estadística de Catalunya, 2012)
    Article
    Open Access
    Visual receptive fields (RFs) are small areas of the visual fie ld where a stimulus induces a re- sponses of a particular neuron from the visual system. RFs ca n be mapped using reverse cross- correlation technique, ...
