Dear Nick, thanks a lot for your kind and helpful hints. Reading across your reply, I notice that In my previous attempts to solve the problem by myself I have mixed up the lines you wrote about -foreach- and -forval- (: Thanks a lot again and Kind Regards, Carlo -----Messaggio originale----- Da: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] Per conto di Nick Cox Inviato: martedì 21 ottobre 2008 19.32 A: statalist@hsphsun2.harvard.edu Oggetto: st: RE: re: a question related to -foreach- Notwithstanding this good advice, it may be of interest to see an answer to the original question. First, as does Kit, I assume that the number of observations is at least 36. This can always be achieved by -set obs- if it is not correct. gen mean = . local i = 1 qui foreach x of var b1-b36 { su `x', meanonly replace mean = r(mean) in `i' local ++i } OR gen mean = . qui forval i = 1/36 { su b`i', meanonly replace mean = r(mean) in `i' } You will want to keep track of names too. For example, gen mean = . gen varname = "" local i = 1 qui foreach x of var b1-b36 { su `x', meanonly replace mean = r(mean) in `i' replace varname = "`x'" in `i' local ++i } Nick n.j.cox@durham.ac.uk Christopher Baum Carlo asks . foreach x of varlist b1-b36 { 2. summarize `x' 3. } I would like to generate a newvar in which the r(mean) for each one of the 36 variables included in varlist are stored. How can I do this in Stata 9.2/SE? No need to use a foreach loop. tabstat b1-b36, save mat mu = r(StatTotal)' mat li mu If for some reason you want these in a variable, use -svmat-: svmat mu which creates variable mu1, obs. 1-36. * * 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/ * * 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/
