Keywords: Auxiliary Information; Calibration Approach; Estimation of Variance; Proportion Allocation; Ratio Estimator; Stratified Sampling.


Calibration has established itself as an important methodological instrument in large scale production of statistics. In this paper, we propose calibration estimation for ratio estimator in stratified sampling and derive the estimator of the variance of the calibration estimation ratio estimator in stratified sampling in case proportion allocation.
