PENAKSIR YANG EFISIEN DARI KOMBINASI PENAKSIR RASIO-PRODUK UNTUK RATA-RATA POPULASI PADA SAMPLING ACAK BERSTRATA

Abstract

In this article we discuss three combined ratio-product estimators for population mean in stratified random sampling proposed by Singh et al. [3]. These estimators are biased so that the Mean Square Error (MSE) for each estimator is calculated to obtain which one is more efficient. This comparison shows that 1 Yˆ estimator is the most efficient estimator among those three
