On Some Modified Class of Ratio Estimators in Simple Random Sampling

Rafia Jan, S. Maqbool

Abstract: This paper suggested an efficient class of modified ratio and product estimators for estimating population mean using auxiliary information. The proposed estimator provides a significant improvement over previous families of estimators in theory and leads to a better prospective of application in various applied areas. The numerical illustration shows that the proposed estimator is more efficient than the existing ones.
