  • Hjort, Nils Lid; Ongaro, Andrea (Research report / Forskningsrapport, 2003)
    A family of nonparametric prior distributions which extends the Dirichlet process is introduced and studied. Such family is first constructed by normalising suitable compound Poisson processes. An alternative derivation ...
  • Hjort, Nils Lid; Ongaro, Andrea (Research report / Forskningsrapport, 2003)
    Two characterisations of a random mean from a Dirichlet process, as a limit of finite sums of a simple symmetric form and as a solution of certain stochastic equations, are investigated. These are used to reach results on ...
  • Hjort, Nils Lid; Ongaro, Andrea (Research report / Forskningsrapport, 2003)
    The Dirichlet process has been extensively studied over the last thirty years, along with various generalisations, and remains a fundamental tool for nonparametric Bayesian statistics. The probabilistic structure of its ...
