摘要：

A new ratio estimator using proposed modified maximum likelihood estimator (MMLE) is suggested. The properties of the new ratio estimator with respect to robustness and efficiency are studied followed by various population models. The employment of proposed MMLE into ratio estimator yields robust estimates, which is very productive for non-normal data or the data contain outliers.
