SOA #21

Hello,

Can someone tell me the following:
1. Can this problem be worked using Negative Binomial as the distribution?

Thank you!

Yes?

Whether it can be worked correctly is another question, and one I'm not equipped to answer since I don't know what the problem is.

Not really. If you use the Buhlmann formulas, the Negative Binomial doesn't arise.

Since Bayes produces the same answer for this problem, you can do it by Bayes. If you insist on using the predictive distribution to get the Bayes estimate---which is easily avoided---then that is Negative Binomial. So you _can_ involve the Negative Binomial, but it isn't at all necessary.

Prof. Daniel,
Thank you! I think this is beginning to make sense.
