Difference-Cum-Ratio Estimators for Estimating Finite Population Coefficient of Variation in Simple Random Sampling

A. Audu, M. A. Yunusa, O. O. Ishaq, M. K. Lawal, A. Rashida, A. H. Muhammad, A. B. Bello, M. U. Hairullahi & J. O. Muili · Asian Journal of Probability and Statistics · 2021

In this paper, three difference-cum-ratio estimators for estimating finite population coefficient of variation of the study variable using known population mean, population variance and population coefficient of variation of auxiliary variable were suggested. The biases and mean...
