| Abstract: | Optimal sampling strategies which minimise the expected mean square error for a linear design as well as model-design unbiased estimators for a finite population total for two-stage and stratified sampling are obtained under different superpopu1ation models |
| Keywords: | superpopulation model finite population two-stage sampling stratified sampling optimal estimator sampling strategy |
