The "Methods and Formulas" of -h ipolate- is quite explicit on the approach
that -ipolate- takes if it doesn`t find appropriate values for x on either
side:

Betreff: st: epolate
I would like to do linear extrapolation for Y for 2008 and 2009 with
ipolate Y X, gen(E) epolate
But I got odd results for 2008 and 2009!! It is going rapidly down
specially 2009. Do I miss something?
