the biased estimate

基本解释

In the sense of the mean-square error, the Biased Estimate can improve the Least Squares Estimation.
有偏估计是牺牲估计无偏性来换取方差的减小。
In this paper, a new biased estimate, which is called the united regression estimate(URE), is proposed for the regression coefficient in multivariate linear models.
本文提出了多元线性模型回归系数的一种新的有偏估计—联合回归估计。
On the basis the parameters are separated for the biased estimate by means of partial prior knowledge, and unbiased estimates of all parameters to be evaluated are obtained.
在此基础上，用部分验前知识，进一步对该有偏估计作了参数分离，从而得到全部待估参数的无偏估计。
