That's why I said "better for a short list". Typing -inlist()- itself has an overhead. Nick n.j.cox@durham.ac.uk Martin Weiss Won`t the typing of the pipe | symbol _and_ the variable name for each comparison get tedious for more than three arguments? -inlist()- requires only an additional comma... Nick Cox I agree with Martin Weiss. -inlist()- in Stata appears to be the equivalent of IN in SAS. I also agree with Anisa Shyti, correcting a typo: cond(x == 3 | x == 4 | x == 5, 1, 0) is another way to solve the problem, but better for a short list. Indeed x == 3 | x == 4 | x == 5 is yet another way to do it, as the expression just above evaluates to 1 or 0 any way. Nick n.j.cox@durham.ac.uk Anisa Shyti let me be more precise: in the condition should be cond(x=3 | x=4 | x=5, 1, 0) - it depend on the condition one needs to set - I was giving a handy example. The cond(.) is pretty flexible. * * 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/
