Good morning,

How do I compute heteroskedasticy-robust F statistic for an OLS regression?

If I use reg with , robust (cluster) 
are the t statistics obtained robust to heteroskedasticity or do I need another command?

Any help on this question will be appreciated (I have been looking at STATa help and FAQ files but I am still not clear on these distinctions)
Thanks
Carola
