I'm working with a database which consists on income by month and
region. I need to classify the income by percentiles by city and month
because there's a wide dispersion on income levels across cities, to the
point that the highest income in one is on the median of another. I know
the command of choice for this task is xtile, but Stata doesn't allow me
to use it with "by" like in "by city date: xtile var=income nq(10)". I'm
working in Stata 9 SE for Windows.
