现在都是使用xtabond2的语法格式: 第一步:定义截面变量和时间变量,语法:tsset province year 第二步:样本的描述性统计,语法:xtsum y x1 x2(注意stata区分大小写,你命名的时候最好统一,否则经常不识别)我们发现统计结果是按照“整体”、“组间”和“组内”三个层次进行的。当然,你也可以采用 sum 命令来得到基本...
对差分GMM与系统GMM的估计,Stata提供了官方的和非官网的两种命令。两者的区别在于官方的命令xtabond与xtdpdsys均不提供异方差稳健的Hansen统计量而是仅仅提供基于iid假设的Sargan统计量,而非官方的命令xtabond2则提供Hansen统计量。Sargan检验不稳健但不受弱工具变量的影响;Hansen检验稳健但容易受到弱工具变量的影响。当工具...
