    with E. M. Airoldi, F. Bassetti, F. Leisen, and M. Guindani
    © 2014, © 2014 American Statistical Association.Many popular Bayesian nonparametric priors can be characterized in terms of exchangeable species sampling sequences. However, in some applications, exchangeability may not be appropriate. We introduce a novel and probabilistically coherent family of nonexchangeable species sampling sequences characterized by a tractable predictive probability function with weights driven by a sequence of independent Beta random variables. We compare their theoretic…Read more
