Betreff: st: egen(more) panel data MA by group/year
Hi all,
I am trying to get a moving average for a group of observations, per
year, in my panel data. The data observations are individuals, each
with an ethnicity. I want to get the yearly average income of those
individuals by ethnicity.
Essentially, I am trying to do this:
egen inc_avg = ma(income), by(ethnicity)
Stata does not seem to allow -by- for -ma-
I also tried
egen inc_avg = ma(income), by(ethnicity) & (year)
Stata doesn't allow & in this context.
Any suggestions?
Thanks,
Steve
