An Alternative Estimator for the Population Mean In PPS Sampling
Journal Title: International Journal of Science and Research (IJSR) - Year 2015, Vol 4, Issue 3
Abstract
In this paper some composite estimators depending on estimated optimum value of a constant based on sample values under PPS sampling scheme have been proposed. The estimators are better in sense(minimum variance) than PPS estimator,ratio estimator or difference estimator under certain conditions.
