On some Ratio and Regression Estimators for the Finite Population Variance in Two Phase Sampling
In this paper, we propose a number of families of estimators of ratio and regression to estimate the population variance using auxiliary information in two phase sampling, the bias and the mean square error expression for the above estimators are obtained up to terms of order only and calculate m...
