Abstract:
|
In simple random sampling, the ratio method of estimation is a well-known technique for estimating the population mean of a study variable when the population mean of the auxiliary variable is known. In this study, a novel ratio estimator based on order statistics is introduced to increase the efficiency of the traditional ratio estimator. It is shown that the proposed estimator is considerably more efficient than the traditional ratio estimator over a very wide family of symmetric distributions. The robustness properties of the proposed estimator are also studied via simulations.
