Hi statalist, When you run a first- difference method, do you always put : noconstant ? For example : reg dx dy, noconstant, or you just run it like OLS . eg : reg dx dy Because I read an article and they put «noconstant» , so I want to know if when we run a first difference, we always put «noconstant» thanks donsaane * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
