algorithms for bounded-influence estimation
收藏 引用
COMPUTATIONAL STATISTICS & DATA ANALYSIS 2007年 第5期51卷 2531-2541页
作者: Bellio, Ruggero Univ Udine Dept Stat I-33100 Udine Italy
Bounded-influence estimation is a well developed and useful theory. It provides fairly efficient estimators which are robust to outliers and local model departures. However, its use has been limited thus far, mainly b... 详细信息
