Modified Regression-Cum-Dual Mean Imputation Schemes for Estimating Population Mean Under Two-Phase Simple Random Sampling

Abstract

In this research, It has been paramount for many researchers under sample survey to use auxiliary information incorporation with the study variables in an estimation stage to modify estimator in order to increase the precision of the estimated population mean. This research work proposed modified regression-cum-dual mean imputation schemes for estimating population mean under two-phase simple random sampling.it concluded that the modified estimators demonstrated a high level of efficiency over the existing estimators considered for both case one and two..
