摘要
Following Searls (1964), we propose an estimator for estimating the finite population variance. This estimator is the combination of Singh et al. (1973), and Prasad and Singh (1992) estimators and has an improvement over Singh et al. (1973), Prasad and Singh (1992), and several other estimators under certain conditions. Validity of proposed estimator is examined by using seven numerical examples.
