无序样品聚类分析——基于斜交空间和平均距离法.

The purpose of the paper was to introduce the basic concepts， calculation methods， two examples and the calculation methods using SAS related to the cluster analysis of disordered samples. Basic concepts included R² statistic， semi-partial R² statistic， pseudo F statistic and pseudo t ² statistic. The calculation methods involved the oblique intersection space distance calculation formula and the average distance calculation formula. The data in the two examples were "population growth and decline data of stem borer in a certain area from 1962 to 1988" and "scores of 10 types of red wines on 6 indicators". With the help of SAS software， cluster analysis of disordered samples was performed on the data in the two examples， and the explanation of the SAS output results was given. [ABSTRACT FROM AUTHOR]
