hi Nicola,

it seems that your answer is usefull for me, too. namely, I asked about how to estimate random effects with robust errors. the question still stays: which Stata version are you using? I can not find command xtscc in my 9.2 version. and what about dashes? could you, please, clarify?

thank you so much.

-xtscc- (remember the dashes!) is useful for both cross-sectional dependence and heteroskedasticity, while fixed effects (it's one of the two options) allows for endogeneity

Dear All,

my panel (N=3D2660 ; T=3D7) presents either heteroskedasticity = (lrtest and xttest3) endogeneity and cross-sectional dependence (xtc= sd test). Moreover there is also serial correlation (xtserial test).
Thank to statalist I found useful commands to correct my analysis bu= t I haven't found a way to cope with all of them together yet.&=
nbsp;The command xtscc for ex. is useful for the cross-sectional dependen= ce (nd maybe also heteroskedasticity..?) but not in the case of endogenou= s covariates. For the endogeneity problem, I tried different commands lik= e ivreg2 and xthtaylor, the last one give nice results in terms of expect= ed coeff signs and their significance, but they don't provide correct SE = for cross-sect dependence. Xtgls seems good for heteroskedasticity (= and serial correlation) but not for endogeneity.
I can say that I'm new with empirical analysis and panel data so eve= ry suggestion or comment would be pretty appreciated.

thanks to all

Ivan
