Improved Estimators of Population Coefficient of Variation under Simple Random Sampling

Rajesh Singh & Anamika Kumari · Asian Journal of Probability and Statistics · 2022

In this article, we suggest some novel estimators of population Coefficient of Variation (CV) of the study variable using the known information on an auxiliary variable like population mean and population variance.  Up to the first order of approximation, formulas for the bias an...
