Hello everyone!

I want to validate logistic regression models of species distrubution
data where presences and absences are weighted differently.
I used lrm from Design package but unfortunately, validate.lrm ignores
weights in the validation process.
Has anyone an idea (package, code) how I can do the validation including

Thanks a lot!
