Staff Introduction
TSUKUDA, Koji / Associate Professor
When a set of individuals with some attributes is partitioned by the attributes of each individual into nonempty and disjoint subsets whose union is the original set, the total number of individuals is expressed as the sum of the number of individuals with each attribute. Expressing a positive integer as a sum of positive integers in this way is called integer partition, and a probability distribution on integer partitions is called a random partition. I am studying random partitions focusing on statistical properties and inferences.
I am also studying regression analysis, which is used to describe associations between explanatory variables and response variables.
Additionally, regarding statistical applications in industry, I am interested in methodologies used for business activities such as development, product design and quality control.
Keywords  Random Partition, Regression Analysis, Statistical Asymptotic Theory
