 note = {古くから他作者説が論じられている『源氏物語』の終わりの 10 巻である「宇治十帖」について，主成分分析およびランダムフォレストといった多変量解析を行い，「宇治十帖」 の作者とそれ以外の諸巻の作者が同一であるかについて，計量的な側面から検討を加える．本研究では，語の使用頻度に対し分析を行い，その結果，「宇治十帖」 の他作者説を支持する積極的な根拠は得られなかった．, This paper focuses on the authorship of "Uji Jujo" which is the closing ten chapters of "The Tale of GENJI". Besides, some researchers consider that their author was not same as the others. The result derived from Principal components analysis and Random forest by word frequency, and we will show that it is obvious different between the chapters and the others. Thus, we will conclude that it is highly possible that the chapters' author was same as the others.},
