The Chain Ratio Estimator and Regression Estimator with Linear Combination of Two Auxiliary Variables
In sample surveys, it is usual to make use of auxiliary information to increase the precision of the estimators. We propose a new chain ratio estimator and regression estimator of a finite population mean using linear combination of two auxiliary variables and obtain the mean squared error (MSE) equ...
