    • Hierarchical models with normal and conjugate random effects: a review 

      Molenberghs, Geert; Verbeke, Geert; Demétrio, Clarice G.B. (Institut d'Estadística de Catalunya, 2017-12-19)
      Article
      Open Access
      Molenberghs, Verbeke, and Demétrio (2007) and Molenberghs et al. (2010) proposed a general framework to model hierarchical data subject to within-unit correlation and/or overdispersion. The framework extends classical ...
    • Some discrete exponential dispersion models: Poisson-Tweedie and Hinde-Demétrio classes 

      Kokonendji, Célestin C.; Dossou-Gbété, Simplice; Demétrio, Clarice G.B. (Institut d'Estadística de Catalunya, 2004)
      Article
      Open Access
      In this paper we investigate two classes of exponential dispersion models (EDMs) for overdispersed count data with respect to the Poisson distribution. The first is a class of Poisson mixture with positive Tweedie mixing ...
    • The new class of Kummer beta generalized distributions 

      Pescim, R. R.; Cordeiro, G. M.; Demétrio, Clarice G.B.; Ortega, E. M. M.; Nadarajah, S. (Institut d'Estadística de Catalunya, 2012)
      Article
      Open Access
      Ng and Kotz (1995) introduced a distribution that provides g reater flexibility to extremes. We define and study a new class of distributions called the Kummer beta generalized family to extend the normal, Weibull, ...
