摘要
引出了参数统计模型下GM估计的一个性质,并进一步证明了该性质与GM性是等价的,从而得到了证明线性估计GM性的一种新的方法,最后由此等价性质讨论了一些线性估计的GM性.
GM estimator is quite important in statistics,but it is very difficult to verify the GM property of a estimator. In this paper,we first get a characterization of the GM estimator under the linear model; thus we establish a method to prove the GM property of a estimator,and then we use this method in some examples.
