Hi everybody!

I have a sample with n=2.000. This sample contains rare events (10, 20, 30
individuals with a specific illness).
Now I'd like to do a logistic regression in order to identify risk factors.
I have several independent variables on an interval
scale.

Does anyone know whether the number of these rare events is sufficient in
order to calculate a multivariate
logistic regression? Or are there any alternative models I should use?
(which are available in R)

Thank you very much any advice!
David
