    • Beta meteorological time series: application to air humidity data 

      Cepeda-Cuervo, Edilberto; Andrade, Marinho G.; Achcar, Jorge Alberto
      Time series models are often used in the analysis of Meteorological phenomena to model levels of rainfall, temperature and levels of air humidity series in order to make forecasting and generate synthetic series which are ...

    • Bivariate beta regression models: a Bayesian approach applied to educational data 

      Cepeda Cuervo, Edilberto; Achcar, Jorge Alberto; Garrido Lopera, B. Liliana
      In this paper we propose a bivariate beta regression model, de¯ning the beta distribution derived from Farlie-Gumbel-Morgenstern (FGM) copulas. This model could be a good alternative to analyze pairs of proportions, when ...

    • Seasonal hydrological and meteorological time series 

      Cepeda Cuervo, Edilberto; Achcar, Jorge Alberto; Andrade, Marinho G.
      Time series models are often used in hydrology and meteorology to model streamflows series in order to make forecasting and generate synthetic series which are inputs for the analysis of complex water resources systems. ...
