| Abstract: | During survey sampling and many other practical problems,there are often missing data. Imputation is one common tool to solve this problem.This paper is devoted to make a review of im- putation methods for missing data.Then,variance estimates of single imputation,simplified calculation of multiple imputation and imputation using response probability are studied.The present problem and development trends of imputation are pointed out in the end. |
