摘要
本文应用现代抗差估计理论，提出了一个抗差有偏估计类（抗差泛岭估计类）并且建立了抗差泛岭估计的计算方法。理论分析和模拟计算表明，抗差泛岭估计具有既可克服法矩阵病态性影响又可抵抗粗差干扰的良好性质。
In this paper, a class of robust biased estimators are established by use of the equivalent weight method. This investigation shows that the most attractive advantage of these new estimators is that they can not only overcome the illconditioning of the normal equation but also have the ability to resist outliers.
