Abstract

In this paper we propose a number of generalized multivariate ratio estimators for two-phase and multi-phase sampling in the presence of multi-auxiliary variables for estimating population mean for a single variable and a vector of variables of interest(s). The expressions for mean square errors are also derived. The suggested estimators are theoretically compared and an empirical study has also been conducted.
