Hi,
(if I am not wrong) and if you want to control for hetereskedasticity you
should use "areg" with options absorb and robust - look command "areg" -
To test for heteroskedasticity, xttest3 calculates a modified Wald statistic
for groupwise heteroskedasticity
in the residuals of a fixed effect regression model, following Greene (2000,
p. 598).
Hope this helps
anna

Subject: st: hetero and autocorr in FE
Hi everybody,
I'm pretty new to stata and I'm trying to check and correct for
heteroskedasticity and autocorrelation in fixed effects model. So far I found
"xtserial" for checking autocorrelation. Any suggestion will be greatly
appreciated!!
Thank you,
L. Surdeanu
