Suppose that each individual in a large insurance portfolio incurs losses according to an exponential distribution
with mean 1/2,where i varies over the portfolio according to a G(a, 3) mixing distribution. The respective
densities of the two distributions are given by
Sx (x) = (1/2) exp (-x/à), x > 0, 2 > 0; S(2) =-
T(a)
2-l exp(-8i), 2 > 0.
Given that the Pareto pdf given by fx (x) =
(5 +x)ª+1 * > 0, a > 0, 8> 0.
(a) Show that the marginal distribution of losses follows a Pareto distribution, i.e. P(a, 5).
(b) Use the mixing formulation of the Pareto to deduce that if X~P(a, 5), then E (X) = .

Bill James's Pythagorean Formula for the winning percentage estimator is given below. wpe = w = [(# runs scored)2]/[(# runs scored)2 + (# runs allowed)2] A team has currently scored 369 runs and allowed 329 runs. If the team does not allow any more runs for the rest of the season, how many additional runs must they score in order to have a wpe of 80%? (Hint: Let x = the number of runs additional scored.)arrow_forward
