The class of Neutral to the Right (NR) priors, (Doksum
1974), contains almost all known families of prior distributions
in the nonparametric Bayesian setting including the Dirichlet
(Ferguson 1973), Beta (Hjort 1990) and Beta-Stacy (Walker and
Muliere 1997) processes. Some curiosities such as characterization
via the posterior, weak posterior consistency and support of NR
priors and, in particular, Beta processes will be discussed.
Explicit connections between Beta and Beta-Stacy processes and
non-trivial connections between the Dirichlet and Beta processes
will be shown.
