Betreff: st: Saving results
Hello,
I have a question about saving individual results while running a loop. I'm
trying to compute the annual state-level gini coefficient across several
states and years, using fastgini. The basic command (in practice, I have a
lot more states and years) is:
foreach s in 6 8 10 {
forval i = 1990(1)2000 {
fastgini var1 if state == `s' & year == `i'
}
}
(Since fastgini doesn't support "by," I can't run "fastgini var1, by(state
year)" and get a table of results.)
What I want to produce is a file that has a column for state, a column for
year, and a column for the gini output. So I figure I need to put something
after the "fastgini var1" line to save each output, but I'm not sure what.
Ideally, I'd like to be able to save each iteration to the same file, just
appending each new iteration to the end of the file. But I could also save
each output to a separate file and append them all at the end.
Some fastgini-specific features that could be helpful:
Running fastgini produces an output like this:
. fastgini var1
gini coefficient = 0.707707707707
According to the .hlp file, fastgini's output is stored in r().
Thanks for any suggestions!
John
