International Journal of Statistics and Applied Mathematics · 2019 · Vol. 4(2) · pp. 22–25
Abstract
Two phase stratified sampling with regression method of estimation using two auxiliary variables has been proposed. An unbiased estimator for the population mean has also been proposed and the variance of the estimator given. Numerical illustration has been presented to show the efficiency of the estimator. The cost function of the procedure has also been given and the optimum variance derived for a fixed cost and sample size
