Some new ratio estimators using coefficient of variation and Kurtosis of auxiliary variate

摘要：

We propose some ratio estimators of a finite population mean using auxiliary variable and obtain mean square error (MSE) equations for all proposed estimators. We find theoretical conditions that make each proposed estimator more efficient than the traditional ratio estimators. In addition, we support these theoretical results with the aid of a numerical example.
