Estimation of finite population variance in successive sampling using multi-auxiliary variables

摘要

In this paper, a general class of estimators for estimating the finite population variance in successive sampling on two occasions using multi-auxiliary variables has been proposed. The expression of variance has also been derived. Further, it has been shown that the proposed general class of estimators is more efficient than the usual variance estimator and the class of variance estimators proposed by Singh etal. (2011) when we used more than one auxiliary variable. In addition, we support this with the aid of numerical illustration.
