摘要
岭估计是从减小均方误差的角度出发而提出的一种有偏估计方法,但是如何确定岭参数目前没有一个公认的良好方法。提出了一种如何确定岭参数的方法,并用算例验证这种方法的可行性。
Ridge estimation is an estimated decrease of the mean square error method biased estimate. However, there is not a recognized good practice to determine Ridge parameters now. This paper proposed a method that how to determine the ridge parameter, and verified the feasibility of this approach with example.
