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…

Fully Data-driven Normalized and Exponentiated Kernel Density Estimator with Hyvärinen Score

Shunsuke Imai, Takuya Koriyama, Shouto Yonekura +2

We introduce a new deal of kernel density estimation using an exponentiated form of kernel density estimators. The density estimator has two hyperparameters flexibly controlling th…

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 $0 < α < 1$ and $θ > - α$ . Especially, we show that the maximum l…
