Followings were findings : 1. Principal component analysis enabled to classify the cases obscurely and to extract the factors contribute to the each principal component. 2. Reversed occlusion cases were classified to 3 groups, which resembled to the clinical classification (skeletal, skeletodental and dental), by the means of cluster analysis. And skeletal cases were devided to 3 groups clearly. 3. Clinical classification of our clinic did not always coincide to the result of cluster analysis and discriminant function analysis, although the classification of skeletal cases was appreciate.}, pages = {179--193}, title = {<原著>反対咬合症例の多変量解析法による類型化の試み}, volume = {3}, year = {1984} }
