Outline of Final Research Achievements

We compared the accuracy of Bootstrap method (BST), Parametric Bootstrap method (PBST), and Bayesian Bootstrap method (BBST) in hypothesis testing of the mean of the two normal populations. According to the simulation results, it is confirmed that the accuracy of PBST is higher than the other two methods.
We also attempted to apply the resampling method to the selection of certification policies in automated reasoning problems. We use the resampling method to narrow down the number of proposed rules and make it possible to reduce the number of rules to a realistic number. The use of statistical methods to eliminate new nonsense ideas, which have exploded in number and appearance, in automatic verification led to the start of a new study on statistical learning.

Academic Significance and Societal Importance of the Research Achievements

ブートストラップ法(BST法)は,遺伝子解析や分子系統樹の作成など,医療・生命分野に利用されており,今後更なる適用範囲の拡大が予測される手法である.しかし,リサンプリング法が内包する標本への過敏性を考慮し,ビッグデータへの適用を鑑みるならば,多変量データに関する統計量分布の問題を回避することは難しいと思われる.本研究において,BST 法の一般型とも言えるベイジアン型リサンプリング法を多変量データへ適用することにより,その研究成果から,多変量データを扱う上でのリサンプリング法適用上の問題点や,適用が難しい統計量などが明確に示されることが予想される.
