st: Why isn't "Robust" available to xtivreg (random effects)?

[Suoqiao Li <tiesuoqiao@hotmail.com>]

Dear Statalist,

I just wonder why there is no "robust" or "vce(robust)" option in xtivreg for RE estimates. Using option VCE(Jacknife) or VCE(bootstrap) is too slow. On the other hand, there is no package similar to ivhettest that can handle heteroskedasticity test after xtivreg. Is there any option other than using VCE(jacknife) or VCE(bootstrap)?

Any suggestion? Thanks,

Suoqiao‏
