Thank you, this is exactly what I was looking for. -- Jennifer L. Milosch Ph.D. Candidate Dept of Economics UC Santa Barbara Quoting Nick Cox <njcoxstata@gmail.com>:

For a detailed review of this and similar problems, seeSJ-9-1 pr0046 . . . . . . . . . . . . . . . . . . . SpeakingStata: Rowwise(help rowsort, rowranks if installed) . . . . . . . . . . .N. J. CoxQ1/09 SJ 9(1):137--157 shows how to exploit functions, egen functions, and Mata for working rowwise; rowsort and rowranks are introduced Note that -egen-'s -rank()- function is not producing incorrect results; it just does not produce what Jennifer wants and does not claim to. It ranks observations on the values of a variable, not variables on the values of a set of variables in each observation.

I have tried using -bysort x1 x2 x3 x4: egen rank1=rank(x1)-but it is returning a variable of all ones, which is not correct.Using thedata above, I'm look for variables that are: rank1|rank2|rank3|rank4 2 |4 |3 |1 3 |1 |4 |2* * 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/
