SUMMARY.  In this article the properties of variance estimators of combined ratio estimator $\={y}_{RC} =  \={y}_{st}\=X/\={x}_{st}$ are studied. The two estimators considered are the conventional and the balanced half-samples variance estimator are unbiased to the first approximation. The mean square errors (MSE) of the two estimators are evaluated.

AMS (1991) subject classification.  62D05.

Key words and phrases. Combined ratio estimator, conventional variance estimator, balanced half-samples variance estimator, mean square error.
