摘要：

In this paper an attempt to estimate the current population mean in two-occasion successive sampling has been made. A modified regression-type estimator has been proposed. Optimum replacement strategy of the proposed estimator has been formulated. The proposed estimator is compared with sample mean estimator when there is no matching from the previous occasion and the optimum natural successive sampling estimator. Empirical studies are carried out and suitable recommendations have been made.
