A treatment pathway, a capital allocation, a health technology assessment.

Decision Tree Pro is built for models that get picked apart in review, and hold.

01

Decision Tree Maker & Analyzer Software with Intuitive User Experience

Build decision trees with chance nodes, utility functions and Markov models. Run Monte Carlo simulation and sensitivity analysis, compute the expected value of perfect information, and produce cost-effectiveness and QALY outputs for health technology assessment. A one-time purchase for Windows, with reports and charts for committee review.

Because you do not deserve the pain of a poorly designed, boring, and awkward user interface for Decision Analysis, SpiceLogic has brought you the most Intuitive and beautiful wizard-like Decision Tree Analysis Software. The user experience is intuitive enough so that you don’t need to learn through a manual. You can intuitively guess the correct way to achieve what you want to model.

03

Create a Markov Chain, simple or complex, directly into the tree.

As a healthcare student, you will be glad to know that, you can model your Markov chain within the Decision Tree analyzer. You can add Rewards to a state to turn your Markov Chain into a Markov Decision Process. You can add multiple Markov nodes and complicate the decision model as you wish.
