Hi,

Trying to setup a logistic regression model.  (Something new to me. I 
usually use SVM.)

The person explaining the concept explained to me that I can include a 
"group" variable so that the probabilities predicted by the model will 
be "per group"

Does this make sense to anyone?  If so, how would I implement this?  
Using the glm or lrm function?

Thanks!
