Outline of Final Research Achievements

I studied the selection of objective priors in Bayesian statistics. In particular, I derived objective priors and studied these properties for non-regular models by using three approaches. As a related study, we studied the theory and methodology for robust Bayesian inference with my collaborators.

Academic Significance and Societal Importance of the Research Achievements

ベイズ統計学においては事前分布の選択が重要であり,理論的根拠を備えた事前分布の選択法はベイズ統計学の客観的な利用において必須である.特に,理想的な条件が成り立っていない非正則な状況は実際問題では自然であるが従来の統計理論が使えないため,事前分布の観点から新たな知見を与えたことは意義あることである.
