Estimation of Population Mean in Chain Ratio-Type Estimator under Systematic Sampling

الملخص EN

A chain ratio-type estimator is proposed for the estimation of finite population mean under systematic sampling scheme using two auxiliary variables.

The mean square error of the proposed estimator is derived up to the first order of approximation and is compared with other relevant existing estimators.

To illustrate the performances of the different estimators in comparison with the usual simple estimator, we have taken a real data set from the literature of survey sampling.
