A Species Sampling Model with Finitely Many Types

Alexander Gnedin, Utrecht University


Abstract
A two-parameter family of exchangeable partitions with a simple updating rule is introduced. The partition is identified with a randomized version of a standard symmetric Dirichlet species-sampling model with finitely many types. A power-like distribution for the number of types is derived.
