That's a dopey example of mine. If you want to map 1 -> 1, 2 -> 2, 3 -> 3, everything else -> 4, you can do it more concisely. The point is just to mention nesting. Nick Cox Your last question is about intention -- what was in the mind of the program designers -- and is perhaps best answered by StataCorp. Oddly enough, I've never used the four argument case that I can recall. Although some dislike the usage, nesting of -cond(,)- lets you handle four or more branches, and I find that more congenial, e.g. cond(x == 1, 1, cond(x == 2, 2, cond(x == 3, 3, 4))) Naturally there are many other ways to achieve similar results. .Nick n.j.cox@durham.ac.uk Visintainer, Paul Nick, Thanks for the coding suggestions. This is exactly what I was looking for--especially for the multiple variables. And, Nick (Winter), thanks for the explanation for cond(). One question: was it the intention of the 4-level cond() to code for missings or is there some other application for it? * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
