Estimation of Population Mean Under Successive Sampling Scheme when Various Weights and Regression Coefficients are Unknown

Abstract

SummayIn this paper properties of an estimator of the population mean on current occasion under successive sampling scheme, when various weights (9h.s) and regression coefficients (BA.h-1) are estimated for A ~2 , have been studied. Some empirical results on the estimation of the variance of an unbiased estimator of population mean for A = 2 are also given.
