چکیده
|
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.
