Abstract

In this paper, we define the estimator of the finite population mean vector of several principal variables under stratified sampling design, in the situations where mean vector of the auxiliary variables is known. An optimum estimator by using the criterion of preference given by Tripathi and Chaubey (2000) has been obtained.
