This is not more complicated than in your first. Sounds like replace ... = myindex * factor1 if inrange(year, 1960, 1980) replace ... = myindex * factor2 if inrange(year, 1981, 2000) Nick On Sat, Sep 10, 2011 at 1:26 PM, Muhammad Anees <anees@aneconomist.com> wrote: > What makes my required computation somehow complicated for me is to > convert a single VARX series divided into three segments like > 1960-1980 (in 1960 units), 1981-2000 (in 1980 units) and 2001-2010 (in > 2000 units).
