Abstract

The work presented in this paper is based on the work of Shukla and Dubey (2001), relating to mean estimation in mail surveys under PSNR (Post Stratified non response) sampling scheme. An alternative estimator has been proposed for estimating the population mean, under the similar set up, using auxiliary information. The bias and approximate variance of the estimator have been derived and compared with the estimator of Shukla and Dubey (2001). It is found that the bias of proposed estimator is very small and it is more efficient. The cost analysis is incorporated to estimate the optimal sample size. Theoretical derivations are numerically justified.
