A NEW RATIO ESTIMATOR FOR FINITE POPULATION MEAN IN DOUBLE SAMPLING

摘要

This paper presents a new ratio estimator for estimating finite population mean using auxiliary information in double sampling based on the Prasad (1989) estimator. We obtain mean square error (MSE) equation of proposed estimator and show mat proposedestimator is more efficient man traditional ratio estimator in double sampling as suggested by Sukhatme (1962) in all conditions. In addition, this theoretical result is supported by the three numerical illustrations.
