Look at the help for -egen- to see how to generate variables containing
summary measures, in this case percentiles. Then your dummies follow
easily.
Type -return list- and study the manual entry to see what is left in
memory after -summarize-.

I was wondering if somebody could tell my how to get the 75th percentile
of a variable and then use it for a future calculation. So,
specifically, using a cross-sectional time series data set organized by
country and year, I want to do the following:
By year, generate a variable with the 75th percentile value for
SqMilesOfLand
Then generate another variable =1 if the current value for a country of
SqMilesOfLand > 75th percentile.
Then I want to do the same thing for less than the 25th percentile, and
another dummy for being between the 25th and 75th percentiles.
A more general question is that I can't figure out how to call out saved
values from something like summarize and use them in future
calculations.
