Chain Ratio-Type and Exponential Chain Ratio-Ratio-Type Estimators in Double Sampling for Stratification

In this paper, we have suggested chain ratio-type estimator, exponential chain ratio-ratio-type estimator, improved estimator and a general class of estimators in Double sampling for stratification for finite population mean. Different conditions were obtained under which the proposed estimators perform better than unbiased estimator, ratio-type and product-type estimators and ratio and product-type exponential estimators. An empirical study is carried out to demonstrate the performance of the proposed estimators over existing estimators.
