强影响的分布与稳定性度量

Distribution and Stability Measure of Influence

中文摘要:

      本文考虑了数据集在样本空间的影响分布,并且指出数据集仅对与之强相关的数据点有较大的影响,因而Cook距离(?)中这一部分数据处的影响较突出,我们考虑用(?)作为影响度量将更合理,同时它也比Cook距离具有更好的稳定性。

英文摘要:

      In this paper, we propose the influence distribution of data sets in the sample space, and show that data sets only have bigger influence in the data case which is strong correlation with, so it′s more prominent that the influence of the partdata in Cook-distance.We propose a new influence measure, namely,(?), it's morerational and robust than D_i( X′X,c).
