Abstract
This paper develops simple and efficient procedures for sampling approximations of the two-Parameter Poisson-Dirichlet Process and the normalized inverse-Gaussian process. We compare the efficiency of the new approximations with the corresponding stick-breaking approximations, in which we demonstrate a substantial improvement.
