Regression-type estimators using two auxiliary variables and the model of double sampling from finite populations
- 129 Downloads
In this paper, we use two auxiliary variablesx andy to construct two regression-type estimators for the population mean of the study variabley. The efficiency of the proposed estimators is investigated under a super-population model. A numerical study is done to demonstrate the practical use of different estimation formulae and empirically demonstrate the performance of the constructed estimators.
