The Method of Cluster Analysis with Missing Data
摘要
传统的聚类分析方法需要完全数据集
但有些情况下数据是不完全的
即包含缺失数据
这给聚类分析带来了一定的困难.作者给出了一种迭代算法为缺失数据确定一个合理的替补值
构造出一个"完全"的数据集
逐步迭代进行聚类分析
并用实例详细阐述了该方法的步骤.
Abstract
The complete data are needed for the traditional cluster analysis. If the data set includs missing data
it is difficult to use the cluster analysis. Anterative algorithm is offered to determine the rational substitute valves of the missing data. After getting a \!complete\" data set
the cluster analysis is iterated step by step. The example is also given to illustrate the step of this method.
