## 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 .

Other comments and suggestions will be appreciated. Thanks!
