Monika Saini, Shashi Bahl . Estimation of Population Mean in Two Stage Design using Double Sampling for Stratification and Multiauxiliary Information. International Journal of Computer Applications. 47, 9 ( June 2012), 17-21. DOI=10.5120/7216-0011
For estimating the population mean of the heterogeneous population, when sampling frame in strata and the strata weight are not defined, we have proposed new difference and ratio estimators using double sampling for stratification and auxiliary information in two stage design. The expression for bias and variances of the proposed estimators have been obtained based on double sampling for stratification approach and comparison have been made with estimator under unstratified double sampling. In addition, we support these theoretical results by an empirical study.
