I am working with a patient dataset which contains
information on each admitted patient as well as on the
according hospitals. For further steps I need a rank number
for each hospital according to admissions per year. The
variable "admissions" already exists. As for each hospital
there are a couple of thousand observations (i.e. patients),
I can not just use egen ranking = rank(admissions), as this
would try to rank each individual observation.

Is there any way to generate a variable ranking that gives
in each observation the same rank for one particular
hospital?
bys hospital_id: gen byte first = _n == 1
gen nonfirst = !first
sort admissions hospital_id notfirst
gen long hospital_rank = sum(first)

Hope this helps,
Maarten
