This is often asked. As explained in e.g.
http://www.stata.com/statalist/archive/2013-03/msg00028.html there are
at least two solutions.
1. Write your own loop.
2. Use the -egen- function -xtile()- by Ulrich Kohler from -egenmore- (SSC).
That said, decile groups for _independent_ variables -- and separately
for 120 periods! -- just sounds like throwing away information, and I
advise against throwing away information.
