Abstract:
We have to proposed combination of two exponential ratio type estimators for estimating population mean using auxiliary variable with double sampling in presence of non-response and study its properties like as mean square error (MSE) and bias. An illustration of the proposed estimator has been made with the relevant class of estimators for optimum value of α.
