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. SB

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^3a^3)/[3(ba)], but you show (b^3a^3)/[2(ba)]. 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) Last edited by chipper28; 03202008 at 02:21 PM.. Reason: give values
