Abstract
This study is devoted to obtain an ecient estima-tor for population mean in two-phase sampling using two auxiliary variables following Vishwakarma and Kumar (2014). Expressions for bias and mean squared error(MSE) are obtained to rst or-der of approximation. The new proposed estimator is compared with some competitor estimators both theoretically and numeri-cally using eight dierent data sets. It has been shown that the new proposed estimator gives more ecient results as compared to its competitor estimators.
