Dual to Ratio-Cum-Product Type Exponential Estimator of Finite Population Mean

摘要

This paper deals with the problem of estimation of finite population mean in simple random sampling. In this paper, dual to Singh et al. (2009) estimator has been suggested. The bias and mean squared error expressions of the suggested estimator are obtained up to the first degree of approximation. The suggested estimator has been compared with simple mean estimator, usual ratio and product estimators, dual to usual ratio and product estimators given by Srivenkataramana (1980), Bahl and Tuteja (1991) estimators and dual to Bahl and Tuteja (1991) estimators given by Tailor et al. (2013). An empirical study has been carried out to demonstrate the performance of the suggested estimator.
