st: RE: using value of one variable to read value of specific other variable out of a list of variables |

gen z = cond(y == 1, x1, cond(y == 2, x2, x3)) Nick n.j.cox@durham.ac.uk arne.weiss@uni-erfurt.de I want to create a variable (z) that contains the value from one variable out of a list of variables (say x1 - x3) depending on the valuable of another variable (y). The list of variables is a) named in a way that the value of y could be used to refer to the correct name of the variable and b) ordered so that the value of y could also be used a locational reference (as the offset command does in Excel). I don't think b) could work in STATA, but I couldn't find a solution for a) either. See below an example. Therein, z in the first row is supposed to be 1 and in the second row 5 (if y = 2, z is supposed to have the value of x2). x1 x2 x3 y 1 2 3 1 0 5 4 2 Here is the closest I came towards a solution: local a = y gen z = x`a' This command, however, only does half the job as the value of the local a is not being rest for every row. I would be very happy for any advice. * * 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/
