Outline of Annual Research Achievements

本研究では,探索的データ解析の側面と数理統計学的側面の両面から,多変量正規性検定方式の開発を行う.代表者らの成果も含めた一変量の正規性検定方式に関する既存結果を発展させることを念頭におきつつ,第一は一変量正規性検定でのqq プロットのような多変量正規性検定のためのグラフ表現法を開発する.第二は,帰無仮説のもとでの多変量標本歪度・尖度の精密分布の導出(もしくは正規化変換等の近似分布の導出)である.この2点を念頭に,一変量の正規性検定方式に関する結果を3編の論文にまとめ,掲載された.なお,第一の目的に関してはAの論文が,第一の目的に関してはB,Cの論文が該当する.
