You're correct. building on Jeph's solution: clear set obs 10 g x=rnormal() g y=x[int(_N*uniform())+1] li Antoine Austin Nichols wrote:

Antoine Terracol <terracol@univ-paris1.fr>: Except the poster wanted resampling with replacement, so you need to generate a random obs to draw from (for each obs) from the integers 1 to N (not simply randomize the order of obs). Look in bsample.ado for a "fast method for resample of size _N" On Thu, Feb 26, 2009 at 2:12 PM, Antoine Terracol <terracol@univ-paris1.fr> wrote:In addition to -bsample- and -merge-, another solution is: clear set obs 10 g x=rnormal() g rnd=uniform() egen rank=rank(rnd) g y=x[rank] li drop rank Antoine Florian Wakolbinger wrote:Dear all, is it possible to randomly draw numbers out of a variable x and write it into another variable y i.e. if x 1 2 3 4 5 then y could be, for instance y 3 5 3 2 4 all numbers in y are randomly drawn from x. how is it possible to construct such a variable y in stata? thanks, and kind regards florian* * 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/
