以下两个命令究竟有什么区别呢?
- reghdfe citations funding, a(year inventor_id)
- reghdfe citations funding, a(year inventor_id) group(patent_id) individual(inventor_id)
第一个命令是我们常用的指令,控制了时间固定效应和inventor_id固定效应,第二个控制的是什么固定效应呢?代码的作者说这叫group-level outcome with individual fixed effects.
不太理解这里控制的究竟是什么?它背后的模型该怎么写呢?
哪位大神能给予解答一下?谢谢
