摘要
Abstract
The purpose of the paper was to introduce the basic concepts,calculation methods,two examples and the implementation of SAS calculation methods related to the cluster analysis of disordered samples.The basic concepts included similarity,dissimilarity,metric and non metric type.The calculation methods involved the second set of distance methods(12 in total)for measuring the distance between two samples and the centroid method for measuring the distance between two clusters of samples.The data in the two examples were"survey data on the expenditure of farmers in 16 regions of China in 1982"and"measurement values of 13 sports events on two quantitative indicators".Using SAS software,cluster analysis of disordered samples was performed on the data from two instances,and the SAS output results were explained.关键词
