testing heteroskedasticity for random effects

[Guest]

Hello,
How can we test heteroskedasticity after

xtreg y x1 x2 x3,re

?

Thanks

visual inspection of the residual distribution, I would say.

Thank you Carlo for your reply, so there is no test for random effects? (for example to test heteroskedasticity after fixed effects we use xttest3 command)
