Abstract

In this paper, authors have proposed a class of dual to ratio estimator for estimating the finite population mean in presence of missing values in two-phase sampling design. Two different sampling designs in two-phase sampling are compared under imputed data. The bias and MSE of suggested estimator is derived in the form of population parameters using the concept of large sample approximation. Numerical studies are performed over two populations using the expressions of bias and MSE and efficiency is compared with existing estimators.

Keywords: Estimation, missing data, bias, mean squared error (MSE), two-phase sampling, SRSWOR, relative efficiency
