It looks like I should have just subtracted 3.08
instead of (3.08)^2 . I will post a corrected solution.
Thanks for pointing that out.

Got another: October 16, 2006

October 16, 2006 is a semiemperical empirical Bayes problem. Makes since except I calculate a different value for the second raw moment via empirical estimation. I believe the formula should be (b^3-a^3)/[3(b-a)], but you show (b^3-a^3)/[2(b-a)]. Neither of these formulas produces the value of 239,250 that you show. The first produces 155,333 and the second 233,000. The total variances are therefore different: 106,933 and 184,600 respectively.

Obviously, this flows through the problem and the answers are different.

It seems pretty straightforward and I would have just ignored it if your formula had had 3 in denominator, but since you compute a different value and show a 2 in the denominator, I decided to check.

Thanks for confirming the last one!

(if the divided by 3 is correct, u=220, v=77,666, a=29,266, k=2.65375, z=.4298, and the credibility premium is 157.68)

A apologize for the delay in responding to you.

You are correct about the Oct 16, 2006 question.
Thanks for pointing that out. I will post a correction.
