| 摘 要： | 本文简要介绍了自适应Ｌｐ估计的有关理论和求解方法，并对ＳＬＲ数据的测量误差作了统计分析。发现ＳＬＲ数据的测量误差服从ｐ值不定的ｐ范分布。本文ＳＬＲ数据预处理实例表明自适应Ｌｐ估计能给出比ＬＳ估计更为稳健有效的拟合参数。当观测值粗差高达６６％时，自适应Ｌｐ估计仍能给出可靠的拟合参数，效果明显优于传统的ＬＳ估计。

| Abstract: | Adaptive LP estimation theory and its solution method are introduced in this paper. statistics of SLR data is also done. It is discovered that SLR data belongs to p-norm distribution with inconstant p value. The example of SLR data prior processing indicates that adaptive Lp estimation gives more robust and more effective imitating parameters compare with LS estimation. When gross error proportion is high to 66%. adaptive Lp estimation can still give reliable robust imitating parameters. superior to LS estimation. |
