I have a problem with xtabond, Sargan test. Any model was not acceptable
because Sargan test. I saw Xtabond robust. In this command don’t have a
sargan estimative. When can I use xtabond robust? Is wrong I use xtabond
robust in my case? If is wrong, what can I use(have other command which
would better)?
Have a look at xtabond2.
