IMPROVED EXPONENTIAL PRODUCT TYPE ESTIMATORS OF FINITE POPULATION MEAN

Abstract

In this paper some improved exponential product type estimators have been suggested for estimating finite
population mean using auxiliary information under simple random sampling without replacement when there exists a
negative correlation between the study and auxiliary variable. The performance of the estimators are studied both
theoretically and empirically with mean per unit estimator, product estimator suggested by Robson [2] and Murthy [3]
and exponential product type estimator suggested by Bahl and Tuteja [4]
