Spatial Econometric MethodsIn addition to the omitted variable bias, we also are concerned about the bias or inefficiency of the estimates due to the spatial correlation in the data.
空间经济计量学的方法除被省去的易变的偏心之外的，我们也关注估计的偏心或无效用由于在数据的空间交互作用。
By using panel data and fixed effects regression models, we have developed in this paper a new method which can be used to correct the omitted variable bias in some regression models.
一般的教材或研究文献没有谈及对其如何补救，该文提出一种采用面板数据和固定效应回归来对这种偏差进行补救的方法。
The SEL and the absolute bias approach for parameter design are studied and improved, on the basis of which the variable compartment iteration searching method is advanced in this paper.
对参数设计中序贯淘汰水平法(SEL)和绝对偏差法进行了研究和改进，提出了以SEL法与绝对偏差法结合为基础的自动变间隔迭代搜索法。
To ensure the signal avoids the long, thin, variable path that is the spring, mechanical systems referred to as bias are used.
为了确保信号避免长而薄的可变路径(弹簧、机械系统)，使用了偏置。
Firstly, it is the variable parameter PID which is able to adjust PID parameters online to improve the control performance through non-linear function according to the bias;
