A Difference Ratio-Regression Type Exponential Estimator of Population Mean in Post-Stratification under Linear Transformation of Auxiliary Variable

Nirupama Sahoo, Suman Dash


Following Grover and Kaur (2014) and Rao (1991), we have proposed an exponential ratio-type estimator of the population mean in post-stratification. It has been discovered that our suggested estimator is more efficient than practically every other estimator already in existence that has been defined for the identical scenarios. Moreover, our proposed estimator outperforms several other existing estimators under certain simple conditions. Theoretical results so obtained and the efficiency have been verified by the numerical illustrations. The performance of the suggested estimator is also the subject of a general study.

Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information.
