聚类分析在无回答现象中的应用

The Application of Cluster Analysis In Non-response Phenomenon

对于抽样调查中的无回答现象,本文应用聚类分析方法对辅助变量的数据进行分层,更好地利用了分层后的信息,改进了对无回答变量的估计.将聚类分析与抽样调查结合起来,是一个比较新的尝试,能够更好地解决实际问题中多变量数据的分层问题,进而对提高抽样调查的精度有重要意义.

We apply cluster analysis method to stratify the data of the auxiliary variables in non - response phenomenon, and utilize the information of stratification to improve the estimating of the non - response variable. Our study shows that applying cluster analysis method in sampling can stratify the multi - variable data well and improve the sampling precision significantly.
