st: Breusch Pagan test after xtregar

[Carmen Blanco <blnco.mc@gmail.com>]

Dear statalist,

I have an unbalanced panel data with AR 1. So I estimate with xtregar.

Could someone please tell me if does Stata have an equivalent
Breusch-Pagan LM test to check the relevance of Random Effect to be
incorporated after xtregar?

Thanks
