摘要
影响分析是回归问题中非常重要的一环,对于含有不等式约束的回归问题同样如此.对于有约束的回归问题,我们必须考虑两类影响点以及各种不同情况下的距离定义.本文将针对两类影响点给出判断强影响点的方法.
Influence analysis played a key role in regression problems. For inequality constrained regression problems, influence analysis will be as important as in unconstrained regression. Here we have to consider two types of influential points and have to define several different kinds of distance. In this paper, we will derive a method to check two types of influential points.
