Hello everyone!
My name is Evgeny and i want to ask you to help me.
In my panel data a RE model was choosen as the best model than a FE model and Pooled regression model.
I've conducted tests on autocorrelation, heteroskedasticity and serial correlation.
Those tests gave me a possitive effect of existing those problems.
Tell me please, what the procedure (command in STATA) that considers AR (1), heteroskedasticity and serial correlation???
