On the regression method of estimation of population mean from incomplete survey data through imputation.
Collaborative Research Center 386, Discussion Paper 442
When some observations in the sample data are missing, the application of the regression method is considered for the estimation of population mean with and without the use of imputation. The performance properties of the estimators based on the methods of mean imputation, regression imputation and no imputation are analyzed and the superiority of one method over the other is examined.
