【摘要】 本文就几种常用的稳健估计方法剔除一二个粗差的情况进行了探讨并得出一些结论。对于其中L~1范数最小法及Huber法的情度评定及统计性质提出了一些论证及计算公式,这些公式可用于实践。本文还对稳健估计方法用于确定形变网中的拟稳点及形变量进行了试算,得出了比较满意的结果。更多还原

【Abstract】 This paper discussed, detecting one or two gross errors in observations several usual robust methods. The statistics property of L~1 estimate and Huber estimate, and formula of its location parameter covariance matrix are introduced. Besides, the paper uses robust methods to study the stable points and deformation problems in deformation net. A satisfactory conclusion has been reached.更多还原
