Outline of Final Research Achievements

The largest results in this study are a progress of the inference problem for parameters of Cauchy random variables. We have established lots of theories for unbiased estimators for the distribution.

Academic Significance and Societal Importance of the Research Achievements

従来推定論の応用ではガウス分布が多く用いられているが、必ずしもそれは常に妥当とはいえず、コーシー分布のような除外値許容的分布の方がふさわしい場合もある。当研究によってコーシー分布が実用的問題へ応用できるようになった。また学術的にはこの研究を通じて擬算術平均をはじめとする多くの数学的成果がコーシー分布を典型例として得られた。
