Title

Mean Estimation under Imputation based on Two-Phase Sampling Design using an Auxiliary Variable

Keywords

Bias, Mean squared error, Two-phase sampling scheme, Relative efficiency

Description

The present article offers more efficient imputation based estimators of the population mean under the framework of two-phase sampling in presence of an auxiliary variable. The theoretical conditions stating superiority of the proposed estimators, over some prevalent existing competitive estimators, in terms of relative efficiency is established by numerical illustrations based on three different data sets from the classical statistical literature.
