I have silmiar question as well.
My guick guess -- this should depend on your theory?  when I use xtabond2, I put lag dependent variable as endogenous variable.

I am using xtdpdsys command at the moment but I didnt assign endogenous and predetermined variables...

没有高手吗？？？？？？？？？

我也不知道

我也想知道

书上和手册都有。
大家都不看的吗？
