XTDPDGMM: new Stata command for efficient GMM estimation of linear (dynamic) panel models XTDPDGMM有teffects选项,可以自动添加相关的时间模拟。 XTDPDGMM:用于线性(动态)面板模型的有效GMM估计的新Stata命令 7 The coefficient of the lagged dependent variable is close to 1. This means that a large amount...
Stata’s newgmmcommand makes generalized method of moments estimation as simple as nonlinear least-squares estimation and nonlinear seemingly unrelated regression. Just specify your residual equations by using substitutable expressions, list your instruments, select a weight matrix, and obtain your results...
具体参见Stata corporation, 2001, STATA 7 Reference H-P, Stata Press 1,含义:“The null hypothesis is that the efficient estimator is a consistent and efficient estimator of the true parameters. If it is, there should be no systematic difference between the coefficients of the efficient estimator ...
所以做法应该是(STATA的命令): sort code year (排序) tis year (时间变量是year) iis code (表示单位的是code) xtreg y x x2, fe(假设其中x是需要被工具的变量) est store fixed (在STATA里命令有变化,不再是HAUSMAN,SAVE了,这里的fixed实际上就是个变量名,用什么都行) xtreg y x x2, re hausman ...
在Stata输入以下命令,就可以进行对面板数据的GMM估计。 . ssc install ivreg2 (安装程序ivreg2 ) . ssc install ranktest (安装另外一个在运行ivreg2 时需要用到的辅助程序ranktest) . use"traffic.dta"(打开面板数据) . xtset panelvar timevar (设置面板变量及时间变量) ...

In our example (and only for the sake of understanding the Stata commands) we may decide thaitnovn, lfydi, loandsportfolaiore correlated with the unobserved country effects while all other instruments are not. In this case the Stata command and output are the following: xtabond2 inv l.inv ...
