Hello Fellow Listeners,
I have a question regarding the use of the command countfit...how does
the command manage "exposure", is this built in the command or must one
add it manually as you would when running a count model outside of the
countfit command. If so, what is the best way to do this for the
command?
I have tried many different approaches and I can not seem to get
countfit to replicate the same outcomes as when I compare the PMR, NBRM,
ZIP and ZINB separately.
Thanks
Franklin
