动态面板数据模型被广泛应用于经济学和社会科学领域,其中GMM估计(Generalized Method of Moments estimation)是其中一种常用的估计方法。GMM估计方法适用于含有内生性问题或测量误差的多期数据模型,它利用样本矩条件等式将矩条件矩阵与参数矩阵进行匹配,从而得到一致且有效的估计量。在动态面板数据模型中,时间维度上的内生...
此处,估计量μ^被称为矩估计量( the method of moments estimator ),简称 MM 估计量。这是因为,该估计量的构造以母体矩条件( population moment condition )为基础,进而用其样本矩条件(依赖于我们使用的数据)做等价代换。因为我们从总体矩条件开始,然后运用类比原理得到一个依赖于观测数据的估计量。 2.1 PMC 和 ...

1 Overview Model过程可以分析线性、非线性（对参数或者对变量）的单方程和方程组。使用的估计方法有：OLS, 2SLS, SUR, ITSUR, 3SLS, IT3SLS,GMM ,FIML。MODEL过程分析的模型如下：这里，Y是内生变量，X是外生变量，TEHTA是参数。观测到的变量要么是内生变量，要么是外生变量。上面的方程组可以简写为：这个...
In this paper, we introduce the one-step generalized method of moments (GMM) estimation methods considered in Lee (2007a) and Liu, Lee, and Bollinger (2010) to spatial models that impose a spatial moving average process for the disturbance term. First, we determine the set of best linear ...
