It sounds as if you want the correlation between two variables for all panels at the same time. . corr x y if time == 42 is how to get that. Just specify the time you want and the pairs of data points are contemporaneous.

I am especially interested in the correlation between two of my variables. I guess simply using the -corr- command isn't enough as the correlation across time isn't included (right?!). I also tried to use the -xttest2- command after a -xtreg,fe- but I have more than 1700 panels, so that didn't work either and probably I won't know more about those two variables I'm concerned about. The regressions went well but maybe I missed something. * * 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/
