Application Of Auxiliary Variables In Two-step Semi-parametric Multiple Imputation Procedure In The Estimation Of Population Mean

ABSTRACT Multiple imputation procedure is used in handling of item non-response. The imputation procedure is affected by model misspecification and leads to loss in efficiency and biased results. The inclusion of auxiliary variables in the sampling design helps to avoid sensitivity of inference to model misspecification and improves the precision of estimate of population mean. The main aim of this study was to incorporate auxiliary variables in the Multiple Imputation to improve the accuracy of the values imputed and the efficiency of point estimators. The twostep semi- parametric multiple i…
