Unhappy Question #274

The answered provided by SOA is as follows:

S(x) = e^-H(x)

H(x) = 0.5534 (I got this part.)

Nelson-Aalen Estimate = 1/50 + 3/49 + 5/k + 7/12 = 0.5534

---> k = 36.

Just my educated guess, not sure if it's correct.

E((S-1)^2)+ = E(S^2)-1+(fs(0))^2*1

E(S^2) = 3(1*0.3 + 4*0.2 + 9*0.1) = 6

(fs(0))^2 = (0.4^3)^2 = 0.004096

E((S-1)^2)+ = 6 -1 + 0.004096 =...

SOA #107 2.0

Currently the questions asked for E(S-1)+

E(S-1)+ = E(S) -1 + fs(0) X 1

E(S) = 3(1*0.3+2*0.2+3*0.1) = 3

fs(0) = 0.4*0.4*0.4

Therefore, E(S-1)+ = 2.064

Sample Question #238

I suppose I'm not sure why E(x^4) = 24 * thera^4

MSE = E((x^2-thera^2)^2)
= E(x^4) - 2*thera^2*E(x^2) + thera^4

As x ~ expo with mean thera
E(x) = thera; Var(x) = thera^2
-> E(x^2) =...
