Asymptotic Inference for Exchangeable Gibbs Partitions

Takuya Koriyama

We study the asymptotic properties of parameter estimation and predictive inference under the exchangeable Gibbs partition, characterized by a discount parameter $α \in (0, 1)$ and a…

Asymptotic mixed normality of maximum likelihood estimator for Ewens--Pitman partition

Takuya Koriyama, Takeru Matsuda, Fumiyasu Komaki

This paper investigates the asymptotic properties of parameter estimation for the Ewens--Pitman partition with parameters $0 < I^\pm < 1$ and $I^¸ > - I^\pm$ . Especially, we show that the maximu…
