Hi there,
I've got a random sample from a population in which a very small
percentage of elements show a particular characteristic. Those are the
ones I'm interested in for further study.
My approach is to use a logistic regression on that sample to get an
estimated probability of having this characteristic. My question is:
based on that predicted probability, how do I divide my sample into
those elements that are likely to have that characteristic from those
that are not (can I determine some cutoff in the predicted probability)?
Thanks for your input.
Matt.
