Re: st: RE: mvreg with vce(robust)?

["Peter Velte" <run-it@gmx.net>]

The issue is as follows: -mvreg- runs much faster on an 8-core server than a loop of -reg- while generating the same results in my case (balanced panel). I assume that is due to the superior parallelization of the Mata code used in -mvreg-. The only difference is that -mvreg- cannot compute heteroskedasticity robust standard errors.

In practical terms assume the following multiple-equation regression:

mvreg portfolio1 portfolio2 portfolio3 = rmrf smb hml mom

Now, instead of ordinary standard errors I want to compute heteroskedasticity robust standard errors for each of the three regressions
portfolio1 = rmrf smb hml mom
portfolio2 = rmrf smb hml mom
portfolio3 = rmrf smb hml mom

Hope that clarifies my question.

Thanks,
Peter
