Sorry, I should have mentioned that you need to scale the matrix: . su z Variable | Obs Mean Std. Dev. Min Max -------------+-------------------------------------------------------- z | 9 .4411562 .2579396 .0610638 .684176 . mat matrix = matrix * r(mean) Nick n.j.cox@durham.ac.uk Nick Cox There have been several elaborate solutions to this, but a very simple one may be enough -- using an official command only. I gather that each row and column combination (var1, var2) occurs once only. That being so, note that tab var1 var2 [aw=var3], matcell(matrix) yields a matrix. But see help on -limits-. Allan Joseph Medwick I have three variables (var1, var2, var3). I would like to create a matrix where the values of var1 are the columns (ascending), the values of var2 are the rows (also ascending), and the values of var3 are the elements in the matrix. I know there must be a user defined procedure out there to do this, but I haven't been able to find it. * * 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/
