: Several estimators of variance of the ratio estimator in simple random sampling have been proposed in Cochran (1977), Fuller (1981), Royall and Cumberland (1978), Royall and Eberhardt (1975), Wu (1982). Their performances are compared on nine populations that reflect different features of natural populations encountered in practice. One criterion is the mean square error of the variance estimator as a point estimator of the variance of ratio; the other is the reliability of the associated t-interval. (Author)

Estimation of Variance of the Ratio Estimator: An Empirical Study.

18 Ratio and regression estimators

The conventional and weighted least squares estimators and a simplified version of the jackknife estimator for the mean square error of the ratio estimator of a finite population mean are considered The biases and the mean square errors of these estimators are compared under a suitable linear regression model
