摘要: 在经济计量建模过程中,异常值的影响评价与诊断问题越来越显得重要。本文旨在提供异常值对复共线性关系检验、序列相关性检验、异方差性检验、单位根检验等经济计量检验产生致命影响的典型案例,为经济计量学的教学与相关建模理论研究提供有说服力的数据资料。

关键词: 异常值, 复共线性关系检验, 序列相关性检验, 异方差性检验, 单位根检验

Abstract: On the procession of econometric modeling, we should pay much attention to the influence assessment and the outliers diagnostics. This paper focus on giving the typical examples of influence on the econometric modeling from outliers, especially the fatal attacks to multicollinearity testing, serial correlation testing, heteroscedasticity testing and unit root testing.

Key words: Outliers, Multicollinearity Testing, Serial Correlation Testing, Heteroscedasticity Testing, Unit Root Testing.
