摘要
利用曲率方法研究具有结构变化的线性回归模型的局部影响,分别得到了在自变量、因变量和加权扰动下相应的诊断统计量,并通过具体的数值实例说明了本文结论的有效性.
The study was performed by use of the curvature method. The diagnostic statistics under perturbation of explanatory variables, response variable and case weights were obtained respectively, and the effectiveness of the conclusion was verified by a numerical example.
