Two Parameter Modified Ratio Estimators with Two Auxiliary Variables for Estimation of Finite Population Mean with Known Skewness, Kurtosis and Correlation Coefficient

摘要

Consider the two parameter modified ratio estimators for the estimation of finite population mean using the skewness, kurtosis and correlation coefficient of two auxiliary variables. The efficiencies of the proposed modified ratio estimators are assessed with that of the simple random sampling without replacement (SRSWOR) sample mean and some of the existing ratio estimators in terms of mean squared errors. The entire above is explained with the help of certain natural populations available in the literature.
