In the case of a binary variable, you could use the shortcuts


*************
sysuse auto, clear
regress price weight length if foreign
regress price weight length if !foreign
*************

to include all foreign (first case) or domestic (second case) cars.

Betreff: st: Exclude some observations from a sample in a regression

Hello,

Doing a regression, I would like to exclude a series of observations 
that are identified with a binary variable (=1). Could you let me know 
what the syntax would be, if it's doable?

Thank you.

Claude
