Hello everyone.
I would like to create a variable that gives me the cumulative of an
amount by country, like so:
country year quar amount cum_amount
Argentina 1990 1 100 100
Argentina 1990 2 50 150
Argentina 1990 2 25 175
Argentina 1990 2 100 275
Argentina 1990 3 200 475
...
Bolivia 1990 1 25 25
Bolivia 1990 1 30 55
...
Does anyone know a command that would do this without needing to write a
loop?
Thank you!
Adrian
