Hello,
I am estimating a discrete choice model with a sample
that contains a small proportion of ones (less than 5%
of the sample).
I am looking for references on the econometric issues
associated with such samples. I know that
count-R-square-type measures are unreliable for such
models, because the .50 cutoff is a poor naive
prediction rule. I've also seen somewhere that the
logit model may be inefficient in such cases, but I do
not recall where this result appears.
Any suggestions would be greatly appreciated.
Thanks,
Casey
