st: Re: counting patient-days

["Michael Blasnik" <michael.blasnik@verizon.net>]

I think there is a simpler solution than the ones proposed.

gen los=dischargedate-admitdate+1
gen date=admitdate
expand los
bysort patientid: replace date=date[_n-1]+1 if _n>1

you now have a dataset with one observation per patient per day where you 
can count the number of days, etc..
