Abstract: This study proposes a class of ratio estimators of mean for calibration estimation that is more precise and efficient than the linear regression estimator under the stratified double sampling using coefficient of kurtosis of auxiliary variable. Some well-known estimators are obtained under certain prescribed conditions and shown to be special members of this class of estimators. Analytical and numerical results proved the efficacy of the new class of estimators over all existing modified estimators in stratified double sampling with appreciable gains in efficiency at its optimum condition.
