چکیده
|
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. © 2016,pak.j.stat.oper.res. all rights reserved.
