Dear all,

I have two questions with regard to a random effects model. How do I test for heteroskedasticity and autocorrelation in such a model? I know I can use xtgls if there is heteroskedasticity and / or autocorrelation, but I don't know how to detect it.
There is a FAQ entitled "How do I test for panel-level heteroskedasticity and autocorrelation?" at

I am not 100% sure this is what you want, but the question it answers is "I see how one can correct for potential heteroskedasticity across panels using xtgls, but I am unsure of a simple way to test for it."
