| 摘 要： | 在对现有的基于等价权的稳健估计的弊端进行分析的基础上,直接从方差膨胀模型出发,建立起一套基于调整观测量方差-协方差阵的相关稳健估计方法,并通过算例证明其估计思想、模型的正确性和可行性.

| Abstract: | It must be noted that despite robust estimation is maturity for independent observations in theory and practice, the research of robust estimation for dependent observations is just rising, even the maturity theory was not established. The technical method of application must be further discussed. Depending on variance inflation model, a set of self contained theory system on robust estimation based on equivalent variance covariance are established. And a small example is given to verify the robust model proposed in this paper are reliable. |
