A Class of Ratio Estimators of a Finite Population Mean Using Two Auxiliary Variables
In sample surveys, it is usual to increase the efficiency of the estimators by the use of the auxiliary information. We propose a class of ratio estimators of a finite population mean using two auxiliary variables and obtain mean square error (MSE) equations for the class of proposed estimators. We...
