Thank you for your feedback!

Thanks to all of you who responded to our first newsletter with suggestions on how to improve The Tree Files. A majority of responders asked for more "Tech Tips" - so this issue will include two new tips, plus advance notice of our 2007 training schedule, our new consultants database and advance notice of one of the principal features to be included in the soon-to-be-released TreeAge Pro 2007.

The upcoming v2007 release of TreeAge Pro takes the software to a new level of flexibility and customizability. This has been accomplished by integrating into TreeAge Pro 2007 all of the scriptability previously available only to developers of TreeAge Pro Interactive applications. TreeAge Pro users will gain access to the flexible scripting features originally designed for the Interactive version, enabling more powerful linking between TreeAge Pro and programs like Excel that have scripting/macro capabilities. For example, simple Excel macros can be written very quickly that control TreeAge Pro 2007, opening and modifying trees and influence diagrams, and performing custom or built-in analyses.

Watch for more details about the 2007 release in next month's newsletter.

Tech Tip - path probabilities & calculating EVPI

[#1] Displaying Path Probabilities

Q: How can I display "path probability" times "payoff" (i.e., contribution to expected value) at endnodes?

A. There are two sets of changes in preferences:

1) Calculation Method:
* check "Calculate extra payoffs"
* set "Enable payoffs..." to 1 if you have only filled in 1 payoff set

2) Terminal Nodes/Columns:
* Show terminal columns
* Add a "Custom" calculation column, with the calculation:
StateProb() * Node(1)

This will display, during roll back, the product of the payoff and the path probability at each visible endnode. These columns can be copied to Excel by choosing Edit > Copy Special...

[#2] Calculating EVPI in TreeAge

Q: What is EVPI? How EVPI is calculated in a Monte Carlo simulation

Using a Monte Carlo probabilistic sensitivity analysis performed at a decision node, TreeAge Pro can calculate the expected value of perfect information (EVPI) or partial EVPI. This can be used to determine the theoretical maximum value of potentially costly efforts to remove particular uncertainties.
