摘要
介绍了基于L曲线法的抗差岭估计模型及其在抵御系数阵病态和观测粗差影响中的作用,给出了抗差岭估计模型的推导公式及L曲线法确定岭参数的基本原理。最后结合实际算例作出五种方案的计算比较,结果表明:基于L曲线法的抗差岭估计模型能够有效地改善和抵御系数阵病态和粗差观测值带来的影响。
The paper introduced the Robust Ridge Estimation Model on L-curve Method , and its function on the Influence affected by ill-conditioned coefficient matrices and gross er-rors .Giving the formula of Robust Ridge Estimation Model and the basic principle of L-curve Method to determine ridge parameters .In the end ,by calculating the example to make five plans ,it manifests that this model can effectively resist the influence of coefficient ma-trix’s morbidity and gross errors .
