TreeAge Pro 2015, R2.0 is now available. This version includes many new features that you may find useful.

This release includes the following changes to the software.

  • The Markov Info View now provides more visibility into health state rewards and transition rewards when the Markov node is selected.
  • Enhanced the entry of Markov Termination Conditions to make it easier to keep the conditions consistent throughout the model.
  • If tree preferences are set to “calculate extra payoffs”, the Rankings Report now shows results for all enabled payoffs rather than only the payoffs active for that calculation method.
  • New Debug functions allow for more flexibility in generating output for debugging, verifying and validating models.
  • Reorganized Monte Carlo Simulation Output to group secondary reports by their functional purpose.
  • Added the Expected Value of Perfect Information vs. WTP Report to show EVPI across a range of willingness-to-pay values.
  • The Expected Value of Perfect Information Details Report from Probabilistic Sensitivity Analysis was modified to better organize the data to reflect the purpose of the report.
  • Updated functionality to better control over which distributions are sampled or not for Microsimulation, Sensitivity Analysis and EVPPI.
  • Improved quality of graph export images as well as changed the export process to provide more flexibility.
  • Added the new keyword _node_label for reference by debugging functions.
  • Added the new keyword _pre_analysis to allow the execution of commands immediately before the analysis begins.
  • Added alternative parameters option for Weibull distributions.
  • Improved licensing and logging for the TreeAge Pro Network License Manager.
