Abstract

In this paper some improved exponential ratio-type estimators have been proposed for estimating the finite populations mean using auxiliary information on two auxiliary variables in double sampling. The properties of the proposed estimators have been analyzed for independent and dependent samples case under simple random sampling without replacement (SRSWOR). An empirical study is carried out to demonstrate the performance of proposed estimators over Noorul- Amin and Hanif (2012), Singh et al. (2008), Singh and Vishvakarma (2007), and Classical Ratio Estimator.
