Tried your suggestion and it helped a bit. Yet, still the 8-core server is substantially slower than my single core laptop with Stata IC.
Isn't there any regression script, which can calculate multiple Newey-West-robust time series regressions simultaneously/parallely through matrix operations?
If I understand function mvreg correctly it does just this, but unfortunately cannot handle unbalanced panels and cannot estimate Newey-West standard errors. Anyone who knows an extension of mvreg?
Thanks for your help,
Peter
