| Abstract: | 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. |
