A composite class of estimators for a finite population mean using two auxiliary variables in two-phase sampling
Sarvesh Kumar Dubey, Manish Kumar, VN Rai and Ashish Tiwari
A composite class of estimators has been formulated in this paper for estimating the mean of a finite population using two auxiliary variables under two-phase sampling design. The mean square errors (MSEs) of the proposed class and the other well-known pre-existing estimators have been computed to the first order of approximation. The precision of the proposed class of estimators has been compared with various pre-existing estimators. The theoretical results have been accompanied with an empirical analysis using real population datasets, and the percent relative efficiencies (PREs) have been computed for the various suggested estimators.
