TreeAge Pro 2009 includes the following new features...
TreeAge Pro 2009 enhances the following features...
A new distribution type allows sampling from multiple correlated normal distributions. The
correlated normal distributions are created within a single Multivariate Normal Distribution by
providing a correlations / covariances via a TreeAge table. Samples can then be drawn from the
individual correlated normal distributions contained within the Multivariate Normal Distribution.
For details on setting up and sampling from a Multivariate Normal Distribution,
refer to
Tech Note #16. The Tech Note includes instructions and an example.
A new submenu offers more control over the operation of inserting a branch and node. It is
now possible to: a) specify the type of node to be created in the specified direction; or b) to
do an "in-place" insert, which creates a new node of the same type as the currently selected
node and also works better at the root of a clone master or clone copy.
This is a new cost-effectiveness Monte Carlo simulation graphing option. It shows varying
"acceptability" of the possibly changing optimal strategy, as the CE threshold (e.g.,
willingness-to-pay/”WTP”, or weight on effect) is increased.
This feature requires the Healthcare Module (TreeAge Pro Healthcare or TreeAge Pro Suite).
The Tree() syntax now allows visible "subsidiary" trees to be referenced in a master tree
calculation and left "connected" to the last master tree node that called it. Enables debugging
of a subsidiary tree via direct analysis commands (e.g., allows subsidiary tree to be rolled
back based on variable definitions inherited from the calling master tree node/path). To help
visualize the temporary connection, navigation is enabled from the root of the subsidiary tree
back to the calling master node using the left arrow key, and the Variable Definitions
window shows definitions that can be inherited from the currently connected master tree
node/path.
The TreeAgeProLib Object Interface has been enhanced to enable Sensitivity Analysis and to
provide access to the Node Outline.
This feature requires the
Excel Module (TreeAge Pro Excel or TreeAge Pro Suite).
The TreeObj object now includes methods for One-Way and Two-Way Sensitivity Analysis.
The new object methods are described in detail in the TreeAge Object Interface online
documentation.
The NodeObj was enhanced to allow read-only access to a node’s Node Outline property, as
demonstrated below.
- Set nodeX = treeX.GetNodeObj
- Debug.Print nodeX.outline(“”)
- Debug.Print nodeX.outline(“<-”)
- Debug.Print nodeX.outline(“r”)
In the first call, the outline text printed is the same as provided in the Node Outline pane of
the TreeAge Pro window; the second prints only the text of a bound note at the node (if any);
the third prints only the Markov state rewards (up to 9*3 expressions separated by “/”). The
single parameter passed in the call should either be an empty string, or match one of the node
outline syntax “keys” described in Chapter 21 of the user's manual.
The Net Benefits vs. WTP cost-effectiveness Monte Carlo simulation graph has been updated
to show threshold information. An option was added to convert the graph to a strategy graph
display, which clearly identifies the optimal strategy for varying WTP.
This feature requires the Healthcare Module (TreeAge Pro Healthcare or TreeAge Pro Suite).
Under C/E calculations, the 2-way region graph has an option (via Cancel button in Net
Benefits dialog) to calculate Costs and Effects separately, dividing visible regions based on
cost only. If two strategies, users can then use the Graph Options to add isocontour lines to
show ICER thresholds.
The new version corrects the problem of extra lines being drawn when "asymptotes" exist
(i.e., intervals containing changes in dominance and points where ICER is negative
infinity/undefined/positive infinity).
The new version also places thresholds more accurately and correctly draws negative ICER
isocontours where dominance exists. Temporary Net Monetary Benefits calculations are used
to locate thresholds.
This feature requires the Healthcare Module (TreeAge Pro Healthcare or TreeAge Pro Suite).
