Dear Statalist,
I know this is a pretty simple question, but 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.
Any help/instruction would be greatly appreciated.
Dave
