    Foerster Grande, Aline; Pumi, Guilherme; Cybis, Gabriela Bettella (Institut d'Estadística de Catalunya, 2022-12-16)
    Article
    Open Access
    In this work we study the problem of modelling and forecasting the dynamics of the influenza virus in Brazil at a given month, from data on reported cases and genetic diversity collected from previous months, in other ...
  • Compositional combination and selection of forecasters 

    Martín Arroyo, Antonio; de Juan Fernández, Aránzazu (Institut d'Estadística de Catalunya, 2022-12-19)
    Article
    Open Access
    The Split-Then-Combine approach has previously been used to generate the weights of forecasts in a combination in the Euclidean space. This paper extends this approach to combine forecasts inside the simplex space, the ...
  • Missing data analysis and imputation via latent Gaussian Markov random fields 

    Gómez-Rubio, Virgilio; Cameletti, Michela; Blangiardo, Marta (Institut d'Estadística de Catalunya, 2022-12-19)
    Article
    Open Access
    This paper recasts the problem of missing values in the covariates of a regression model as a latent Gaussian Markov random field (GMRF) model in a fully Bayesian framework. The proposed approach is based on the definition ...
  • Alternate-wrapped circular distributions 

    Joshi, Savitri; Rattihalli, R. N. (Institut d'Estadística de Catalunya, 2022-12-20)
    Article
    Open Access
    To generate a circular distribution, we use the alternate-wrapping technique (unlike the usual wrapping), by wrapping in the alternate directions, after each single-wrapping. The resulting distribution is called alternate-wrapped ...
