Beta meteorological time series: application to air humidity data
Cepeda-Cuervo, Edilberto; Andrade, Marinho G.; Achcar, Jorge AlbertoTime 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 ...Universidad Nacional de Colombia Sede Bogotá Facultad de Ciencias Departamento de Estadística. -
Bivariate beta regression models: a Bayesian approach applied to educational data
Cepeda Cuervo, Edilberto; Achcar, Jorge Alberto; Garrido Lopera, B. LilianaIn 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 ...Universidad Nacional de Colombia Sede Bogotá Facultad de Ciencias Departamento de Estadística. -
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. ...Universidad Nacional de Colombia Sede Bogotá Facultad de Ciencias Departamento de Estadística.
