But the point is that i need the respective observations to constitute a variable, not independent scalar. I have tried the following code: egen t=group(year) forvalue t=1(1)11{ gen y`t'=10*exp(2*`t') } gen a=year replace a=y1 if year==2000 replace a=y2 if year==2001 replace a=y3 if year==2002 . .replace a=y11 if year==2010 Please is there a simple code to do this? thank you -------------------------------------------------------------------------------- Would it be something like this? generate double a = 10 * exp(2 * (year - 1999)) Joseph Coveney * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/
