摘要：
In this paper, a generalized ratio-type estimator based on ranked set sampling (RSS) is proposed for estimating population mean using the known population parameters of auxiliary variable. The mean square error (MSE) of the proposed estimator is derived and compared with some existing ratio estimators under RSS. It is proved that MSC of proposed ratio estimator is less than MSC of some existing ratio estimators based on RSS under some conditions. The MSE of proposed estimators along with some existing estimators are also calculated numerically which showed that the proposed ratio estimators is more efficient than some existing ratio estimators under RSS.
