Dear STATA users, I am writing to ask for a general opinion on STATA.
I am running a logistic multilevel model with melogit.
This is a study with 900 patients from 23 hospitals each observed at different timepoints at which I assess the presence / absence of adverse drug events.
The model is also quite simple:
melogit events i.sex age time || center: || id:
Is it normal for this kind of model STATA takes 20 minutes to give me an output?
Or is it a problem with the structure of my data?
When I use only one of the two levels || id: OR || center: the output is immediate
Thank you very much.
Gianfranco
