Daniele Dear Daniele: - I suppose that your question refers to the Compound Average Growth Rate (CAGR). Considering a variable Y (which is assumed to take on the following values: 1 in the first year; 2 in the second as well as inn the third year) followed-up for a three-year span of time, the CAGR formula is. [(Y Value year 3 / Y Value year 1)^(1/3) -1]. - translated into Stata command, it might sound like the following example (please, see below): --------------------------------begin example------------------------------- set obs 3 obs was 0, now 3 gen Year=_n gen Y= 1 replace Y=2 in 2/3 (2 real changes made) gen CAGR=(Y[3]/Y[1])^(1/3)-1 in 3 ------------------------------- end example--------------------------------- HTH and Kind Regards, Carlo * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
