Extending a series

[Riaz]

Hi
I want to extend a quarterly data series called Y which is currently from 1985q3 to 2009q2, by 2 observations: 2009q3 and 2009q4; on its average growth rate (dlog) of the last 3 periods.
Cheers, Riaz

Code: Select all

smpl 2008q4 2009q2 scalar growth = @mean(dlog(y)) smpl 2009q3 2009q4 y = (1+growth)*y(-1)

Something like that should do it.

Thanks
