Dear Statalist
 
This is a simple question. I am using a cross-section data with different firms and workers. I want to run a regression on full-time workers only. Would it be best to put the variable, say, flprt in the regression which indicates whether the worker works full or part-time and using the dummy variable for full-time, frlprt2; where frlprt2=full-time workers. 
 
(2) Or run
 
 y  x1 x2 x3 if flprt==2
 
where frlprt2=full-time workers.
 
Thanks
