摘要
介绍了模糊层次聚类的基本方法与步骤。运用模糊层次对我国部分上市房地产企业的经营绩效进行了聚类。聚类过程中,采用环比评分法确定指标的权重,运用极大极小法构造模糊相似矩阵,通过统计量比较分析,确定了最佳分类数目。结果显示:方法通俗易懂,直观生动,客观准确。
The basic methods and steps of the fuzzy hierarchial clustering are presented in this paper.By using the fuzzy hierarchy,we can cluster the performance of some of the real estates in our country.In this paper,by determining the weight of the indicators by month-to-moth score,using the minimax method,to construct the fuzzy similarity matrix,by means of the statistical camparative analysis,the best classification numbers are determined.The result shows that the method is easy to understand,intutive and vivid,object and accurate.
