Robust regression imputation for analyzing missing data
Missing data arises in many statistical analyses which lead to biased estimates. In order to rectify this problem, single imputation and multiple imputation methods are put forward.

| description | Missing data arises in many statistical analyses which lead to biased estimates. In order to rectify this problem, single imputation and multiple imputation methods are put forward. However, it is found that both single and multiple imputation methods are easily affected by outliers and give poor estimates. This article proposes simple but very interesting robust single imputation technique which gives more accurate estimates over the classical single imputation technique in the presence of outliers. The proposed method is basically the robust version of the classical random regression imputation (RRI) which we call robust random regression imputation (RRRI). By examining the real life data, results show that the RRRI method is more resistance in the presence of outliers. |
