Abstract

This article suggests a model-assisted variance estimator for the ordinary ratio estimator under the Midzuno-Sen sampling scheme. To compare the suggested estimator empirically with available estimators a Monte Carlo comparison is carried out using real populations. The suggested estimator has performed very well and has taken non-negative values with probability 1.

Keywords

M-S sampling scheme Model-Assisted estimator Non-negative variance estimation.
