摘要
将均值漂移模型引入抗差估计,提出一种新的抗差估计模式。根据该方法,可以在抗差处理过程中不对权阵作任何改变,避免出现秩亏矩阵,适于相关观测数据的处理。算例表明,该方法具有很好的抗差性。
The mean shift model for robust estimation and a new robust estimation model were proposed in the paper. In the use of the robust estimation model, it is unnecissary to change weight matrix for avoiding appearance oi the rank deficient matrix. This method is suitable for processing of observation data. Examples show that the pro- posed method has good robustness.
