st: linear interpolation
I know I need to expand by 31,815 observations (1761 for every year
in the 1980s and 1774 for every year in the 1990s).
. local N = `_N' + 31815
. set obs `N'
obs was 5318, now 31815
What I'm trying to figure out now is to assign values of a year for
every 1761 observations through the 1980s, then 1774 for every year
in the 1990s. For instance, to do this:
(where the total is 1,761 for 1981, and the same would be for 82-89,
and 1774 per year for 1991-1999). I don't think using what you
wrote, ". replace year=1975 + _n if year==." will work since I do not
need year increasing with every observation. Does anyone know how to
fill in missing data with such precision?
