Hello,
In first place, thanks to all of you for your useful comments. In second
place, I would like to make two more queries:
1. what is the sense of having a command xtregar, .. re (that corrects
for AR1) when the random effects model is a GLS estimator and can itself
correct for heteroskedasticity and autocorrelation?
2. Does anyone know where can I find the critical values for the Baltagi
LBI test and for the modified Bhargava et al. Durbin-Watson tests that
accompany the command xtregar?
Thanks a lot,
Dolores
