We present a dependent Bayesian nonparametric model for the proba- bilistic modelling of species-by-site data, i.e. population data where observations at different sites are classified into distinct species. We use a dependent version of the Griffiths-Engen-McCloskey distribution, the distribution of the weights of the Dirichlet process, in the same lines as the Dependent Dirichlet process is defined. The prior is thus defined via the stick-breaking construction. Some distributional properties of this model are presented.Abstract (other language)
Presentiamo un modello parametrico bayesiano dipendente per la model- lazione probabilistica dei dati specie per siti, cio ́ e i dati sulla popolazione in cui le osservazioni in diversi siti sono classificati in specie distinte. Usiamo una versione dipendente della distribuzione Griffiths-Engen-McCloskey, la distribuzione dei pesi del processo di Dirichlet, in analogia con la definizione del processo di Dirichlet dipendente. La distribuzione a priori ́ e definita tramite la costruzione stick-breaking. Alcune propriet ` a distributive di questo modello sono presentate.Subjects / Keywords
