Limit theorem associated with Wishart matrices with application to hypothesis testing for common principal components
Koji Tsukuda, Shun Matsuura
This study derives a new property of the Wishart distribution when the degree-of-freedom and the size of the matrix parameter of the distribution grow simultaneoulsy. Particularly,…
Error bounds for the normal approximation to the length of a Ewens partition
Koji Tsukuda
Let be a positive integer-valued random variable whose distribution is given by , where is a positive n…
Weak convergences of marked empirical processes in a Hilbert space and their applications
Koji Tsukuda, Yoichi Nishiyama
In this paper, weak convergences of marked empirical processes in and their applications to statistical goodness-of-fit tests are provided, where $L^2(\mathbb{R…
A reversal phenomenon in estimation based on multiple samples from the Poisson--Dirichlet distribution
Koji Tsukuda, Shuhei Mano
Consider two forms of sampling from a population: (i) drawing samples of elements with replacement and (ii) drawing a single sample of elements. In this paper, under t…
Covariance structure associated with an equality between two general ridge estimators
Koji Tsukuda, Hiroshi Kurata
In a general linear model, this paper derives a necessary and sufficient condition under which two general ridge estimators coincide with each other. The condition is given as a st…
