Direct sampling from conditional distributions by sequential maximum likelihood estimations
Shuhei Mano
We can directly sample from the conditional distribution of any log-affine model. The algorithm is a Markov chain on a bounded integer lattice, and its transition probability is th…
Algorithm for direct sampling from conditional distributions of toric models
Shuhei Mano, Nobuki Takayama
We show that contiguity relations of hypergeometric functions of several variables give a direct sampling algorithm from the conditional distribution of toric models in statistics.…
Asymptotic Moments Matching to Uniformly Minimum Variance Unbiased Estimation under Ewens Sampling Formula
Masayo Y. Hirose, Shuhei Mano
The Ewens sampling formula is a distribution related to the random partition of a positive integer. In this study, we investigate the issue of non-existence solutions in parameter…
Adversarial robust weighted Huber regression
Takeyuki Sasai, Hironori Fujisawa
We consider a robust estimation of linear regression coefficients. In this note, we focus on the case where the covariates are sampled from an -subGaussian distribution with unk…
Robust Persistence Diagrams using Reproducing Kernels
Siddharth Vishwanath, Kenji Fukumizu, Satoshi Kuriki +1
Persistent homology has become an important tool for extracting geometric and topological features from data, whose multi-scale features are summarized in a persistence diagram. Fr…
Dependence Properties of B-Spline Copulas
Xiaoling Dou, Satoshi Kuriki, Gwo Dong Lin +1
We construct by using B-spline functions a class of copulas that includes the Bernstein copulas arising in Baker's distributions. The range of correlation of the B-spline copulas i…
Minimax Predictive Density for Sparse Count Data
Keisuke Yano, Ryoya Kaneko, Fumiyasu Komaki
This paper discusses predictive densities under the Kullback--Leibler loss for high-dimensional Poisson sequence models under sparsity constraints. Sparsity in count data implies z…
On Difference Between Two Types of -divergence for Regression
Takayuki Kawashima, Hironori Fujisawa
The -divergence is well-known for having strong robustness against heavy contamination. By virtue of this property, many applications via the -divergence have been proposed.…
Empirical Best Linear Unbiased Predictors in Multivariate Nested-Error Regression Models
Tsubasa Ito, Tatsuya Kubokawa
For analyzing unit-level multivariate data in small area estimation, we consider the multivariate nested error regression model (MNER) and provide the empirical best linear unbiase…
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…
Optimal experimental design that minimizes the width of simultaneous confidence bands
Satoshi Kuriki, Henry P. Wynn
We propose an optimal experimental design for a curvilinear regression model that minimizes the band-width of simultaneous confidence bands. Simultaneous confidence bands for curvi…
A simple method to construct confidence bands in functional linear regression
Masaaki Imaizumi, Kengo Kato
This paper develops a simple method to construct confidence bands, centered at a principal component analysis (PCA) based estimator, for the slope function in a functional linear r…
Non-area-specific adjustment factor for second-order efficient empirical Bayes confidence interval
Masayo Y. Hirose
An empirical Bayes confidence interval has high user demand in many applications. In particular, the second-order empirical Bayes confidence interval, the coverage error of which i…
Partition structure and the A-hypergeometric distribution associated with the rational normal curve
Shuhei Mano
A distribution whose normalization constant is an A-hypergeometric polynomial is called an A-hypergeometric distribution. Such a distribution is in turn a generalization of the gen…
The Bivariate Lack-of-Memory Distributions
Gwo Dong Lin, Xiaoling Dou, Satoshi Kuriki
We treat all the bivariate lack-of-memory (BLM) distributions in a unified approach and develop some new general properties of the BLM distributions, including joint moment generat…
Equivalence between direct and indirect effects with different sets of intermediate variables and covariates
Manabu Kuroki
This paper deals with the concept of equivalence between direct and indirect effects of a treatment on a response using two sets of intermediate variables and covariates. First, we…
Chi-Square Mixture Representations for the Distribution of the Scalar Schur Complement in a Noncentral Wishart Matrix
Constantin Siriteanu, Satoshi Kuriki, Donald Richards +1
We show that the distribution of the scalar Schur complement in a noncentral Wishart matrix is a mixture of central chi-square distributions with different degrees of freedom. For…
Möbius transformation and a Cauchy family on the sphere
Shogo Kato, Peter McCullagh
We present some properties of a Cauchy family of distributions on the sphere, which is a spherical extension of the wrapped Cauchy family on the circle. The spherical Cauchy family…
Simultaneous confidence bands for contrasts between several nonlinear regression curves
Xiaolei Lu, Satoshi Kuriki
We propose simultaneous confidence bands of the hyperbolic-type for the contrasts between several nonlinear (curvilinear) regression curves. The critical value of a confidence band…
Sparse and Robust Linear Regression: An Optimization Algorithm and Its Statistical Properties
Shota Katayama, Hironori Fujisawa
This paper studies sparse linear regression analysis with outliers in the responses. A parameter vector for modeling outliers is added to the standard linear regression model and t…
Extended Conway-Maxwell-Poisson distribution and its properties and applications
Subrata Chakraborty, Tomoaki Imoto
A new three parameter natural extension of the Conway-Maxwell-Poisson (COM-Poisson) distribution is proposed. This distribution includes the recently proposed COM-Poisson type nega…

Ting-Li Chen, Hironori Fujisawa, Su-Yun Huang +1
This article studies the weak convergence and associated Central Limit Theorem for blurring and nonblurring processes. Then, they are applied to the estimation of location paramete…
