Correction to yesterday's exercise 5.5

In the last part of Exercise 5.5, when computing I_B^3 for p_i=p, I=1, ..., 5, I by mistake wrote a 2 where there should have been a 4. This created an error throughout the remaining part of the exercise. The correct expression is I_B^3 = 2p^2(1-p)^2.

If you plot this and compare with the expressions for I_B^j, j = 1, 2, 4, 5, you will find that components 1, 2, 4 and 5 are more important than component 3 w.r.t. the Birnbaum measure of reliability importance (like we found for the Birnbaum measure of structural importance).

Sorry about the mess-ups, and thank you for correcting me! Next time I'm sick, I'll cancel the lecture instead of screwing up so much. :-)

Have a nice weekend!
