<> Note, however, that there is a hazard involved when specifying a -varlist- that encompasses all variables between "x1" and "xn" via the dash notation: The number of variables between them changes with the -sort- order, as seen after -describe- (see [U], page 101, example 14). So next time you run this code, the result could be different. Issuing an explicit -sort- or -order- could save you trouble. Also note that the -sum()- function would give you a running sum, and accepts only a -varname-, not a -varlist-...

Oktober 2009 19:46 An: statalist@hsphsun2.harvard.edu Betreff: st: sum of many variables Dear Statalisters, I would like to use the sum command, i.e. egen x= sum (x1, x2...xn) however since my n is a large number I would like to indicate that I want the sum from x1 to xn without specifying all variables. Do you have any suggestions? Thank you very much in advance AR * * 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/ * * 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/
