Hi Daniel, Thank you very much for your help. Sorry for not having found the corresponding text via the -help- function before. I actually needed both, counting the number of variables with value "2": egen var1 = anycount(var_101-var_110), values(2) and computing the sum across these variables (sorry for the imprecise question). Thanks & greetings, Philipp ------------------------------ Date: Sat, 3 Dec 2011 13:18:57 +0100 From: daniel klein <klein.daniel.81@googlemail.com> Subject: Re: st: How can I count the number of variables that meet a certain condition per observation? Phillip "would like to count for each observation the number of variables that meet a certain condition, say var*==2." The very first function in -help egen- is -anycount()- and is described as: "It returns the number of variables in varlist for which values are equal to any integer value in a supplied numlist. [...] Also see anyvalue(varname) and anymatch(varlist)." However, I am not sure I am getting the problem, because "[...] computing the sum across variables (for each observation) ONLY for those variables with values greater than 1" to me means something comletely different and is not at all "[...] alternatively, [...]" to "the number of variables with values greater than 1 per observation" Best Daniel * * 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/
