Re: st: xtivreg, re: Autocorrelation & heteroscedasticity

Dear Sergiy,

thanks for your response. I used the xtgls command as suggested in your 
link, while I was not controlling for endogeneity. However, I found out 
that I have to control for endogeneity and followed the suggestion to do 
this with Balestra & Varadharajan-Krishnakumar's (1987) 2SLS model with 
the xtivreg command.
So I can either control for endogeneity with the xtivreg command or I 
control for autocorrelation and heteroscedasticity with the xtgls 
command. However, I would like to control for all three options 
simultaneously.
Is there a command or workaround that is capable to do this? Did I 
misunderstand anything?
Thanks,
Marc
