Abstract
Using two-phase sampling mechanism, a modified generalized exponential estimator of finite population mean in the presence of the available knowledge on the auxiliary variable x is suggested i.e. the population mean of auxiliary variable x is not known. The suggested estimator is found to be more efficient than usual two-phase ratio, product, regression estimators and also modified exponential ratio and product estimator suggested by Singh et.al (2007). Further a numerical study is made to support the theoretical comparison.
