Control Charts for Calibration Estimators in Survey Sampling

Abstract

Calibration Estimators are used to improve the efficiency of the estimators. In this work, we provide some new estimators by using auxiliary information such as calibration ratio estimator, calibration exponential ratio estimator and calibration log ratio estimator. Also, we propose some process monitoring using the proposed estimators. We introduce Shewhart control chart, exponentially weighted moving average control charts and Hybrid exponentially weighted moving average control charts to monitor the process total using proposed calibration ratio estimator, calibration exponential ratio estimator and calibration log ratio estimator
