st: Autocorrelation in 2SLS

["Maria jimenez rubio" <djrubio9@hotmail.com>]

Dear Statalist users,

I am estimating a fixed effectx 2SLS model. Running the fixed effects model 
alone, I have found autocorrelation .  I think ivhettest can be used to test 
heteroskedasticity, so I would like to know if there is another special 
comand in Stata to test for autocorrelation in 2SLS models. Any suggestion 
would be highly appreciated.

Thanks a lot,

Dolores
