Your questions change from post to post....The total of variables precisely equal to 2 is the count of such variables multiplied by 2. Thus the first answer implies the second.

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
