Abstract

In this paper, we introduce estimators for the population coefficient of variation within a two-occasion, stratified, successive sampling framework, aiming to mitigate the impact of non-response and measurement errors. We derive calibrated weights for the strata and thoroughly examine the properties of the proposed estimator through comprehensive numerical and simulation studies. Furthermore, we provide valuable recommendations for survey statisticians, guiding them on effective applications in real-world survey scenarios. By addressing the challenges of non-response and measurement errors within a stratified sampling approach, our proposed estimators aim to enhance the accuracy and precision of coefficient of variation estimates, ensuring more precise and accurate results.
