چکیده
|
Use of auxiliary variables is very common in estimating various population parameters. the information of auxiliary variable has not been encountered in some of studies so two-phase sampling is employed. in literature estimation of population mean, sum and variance is very common in various types of sampling methods. however, variables have a highly skewed distribution, such as income, production is studied median is often regarded as more appropriate measure of location than mean. in this study, we purposed to introduce the ratio, product and regression median estimators in two-phase sampling in literature and examine the efficiency of these estimators both theoretical and practical.
