Hi Statalisters,
I am using a subpopulation of the National Inpatient Sample, about 3million
cases, and looking at different predictors for discharge types (0 = routine
1= died in hospital 2= to SNF/nursing home), controlling with Elixhauser
comorbidities.
Stata can give me results with many of my predictor variables within about
10 minutes. However, when I use an ordinal predictor variable (eg hospital
type small/medium/large), nothing happens, I've left it running for a day
or two without any sign that data will be resulted. Any ideas on what
could be going wrong?
I'm using a Mac with 8g of ram and stata 12.
Here's the basic command function:
svy, subpop(AGE if AGE>=18&AGE<=90): mlogit discharge HOSP_SIZE elix1 elix2
elix3 elix4 ...[through elix 30]
Mike
