Note on calibration in stratified and double sampling - ARCHIVED

In the present investigation, we introduce new calibration equations to estimate the population mean in stratified simple random sampling, making use of second order moments of the auxiliary character. We also suggest ways for estimating the variance of the proposed estimator. The resultant new estimator can be more efficient in stratified sampling than the combined regression estimator. Thus, we have extended the idea to double sampling in a stratified population and have studied the simulation results.
