An Almost Unbiased Estimator of Population Mean Using Multi-auxiliary Variables
Abstract
In this paper, we propose an almost unbiased estimator of population mean using multi-auxiliary variables. We have obtained bias and mean square error (MSE) of the suggested estimator and its efficiency has been compared with all the other existing estimators. It is theoretically shown that the proposed estimator is more efficient than existing estimators under defined conditions. In addition, we support these theoretical results with the aid of a numerical example. Again, efficiency of estimators is compared using simulation technique
