.... element n 1 to the jth class whose current size is n j with probability n j (75) k, and assigning n 1 to a new class numbered k 1 with the remaining probability (76) For # = 0 and # 0 this is generalization of Polya s urn scheme developed by Blackwell McQueen [7] and Hoppe [21]. See [43, 45, 20] for consideration of more general prediction rules for exchangeable random partitions. The following calculation shows how to derive either of the two EPPF s (74) and (66) from the other. The argument also shows that the function p# (n 1 , defined by (66) satisfies the ....

For ff = 1 2 and = 0 the above scheme generates Pi with the same distribution as Pi derived from the excursions of a Brownian motion, while the scheme with ff = 1 2 ; 1 2 generates Pi derived from excursions of a Brownian bridge. According to (86) for each Gamma 1 2 , the ....

....are difficult to describe explicitly, there are some remarkably simple formulae involving this distribution, most notably the Ewens sampling formula [23, 25] Antoniak [3] derived the Ewens sampling formula from the Blackwell MacQueen description of sampling from a Dirichlet prior. Hoppe [35, 37] used the urn scheme to derive the simple form of the size biased random permutation of the pd distribution, which Ewens [24] termed the gem distribution, after Griffiths, Engen and McCloskey, who contributed to its development and application in the fields of genetics and ecology. Dirichlet ....

As a consequence of Proposition 49, the urn scheme for generating pd(0; studied by various authors [8, 26, 28, 14] also admits a two parameter generalization [48] whose simple form provides another characterization of the two parameter family [66] ....
