On the Stochastic Restricted Modified Almost Unbiased Liu Estimator in Linear Regression Model
收藏 引用
Communications in Mathematics and Statistics 2018年 第2期6卷 185-206页
作者: S.Arumairajan Department of Mathematics and Statistics University of JaffnaJaffnaSri Lanka
In this article,we propose a new biased estimator,namely stochastic restricted modified almost unbiased Liu estimator by combining modified almost unbiased Liu estimator(MAULE)and mixed estimator(ME)when the stochasti... 详细信息
