摘要
提出了无偏回归估计方法,从理论上证明了该法比常规的估计法具有更小的平均估计误差。针对脊峰回归估计存在的问题,构建了岭无偏回归方法并讨论了此法的优点与应用前景。
Unbiased regression methods were developed. It was proven theoretically that the estimate errors of unbiased regression estimation are less than that of general regression estimation. After analysing the problems of rigid regression estimation,unbiased rigid regression method was developed and its merits were discussed.
