Amplifications and Corrections

Risk and Decision Analysis in Projects, 2nd edition

Figure 1.9, page 16. While an A/E chart is acceptable, I now prefer the E/A chart. They look and work about the same. If a population pdf is multiplied by an E/A distribution, the result is an Estimate distribution with the same EV as the population. I have used this approach several times in modeling competitive bidding and portfolio analysis.

There is one more mistake in the book. If you find it, please email John Schuyler at john's email address.

Other comments and suggestions will be appreciated. Thanks!
