Free Live training (Zoom or Teams, whatever you prefer)

If you need, we will book a live one-hour one-to-one training session for you, demonstrating the various features of this software. We will walk thru the user interface and show you how to model a problem that you are concerned about.

Cost-Effectiveness Analysis for healthcare

Use QALY or DALY as an Effectiveness payoff into the decision tree. Include Cost and visualize the cost-effectiveness plane. Learn More
cost effectiveness analysis in decision tree for healthcare

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. Learn More

Advanced Utility Function for payoff modeling

Intuitively modeling utility function is one of the features that make this decision tree software stand out from others. It lets you go very deep with shaping rich utility functions. Learn More
Advanced Utility Function Editor

Perform Sensitivity Analysis

Sensitivity analysis is a crucial part of decision analysis. A decision won't be robust until a sensitivity analysis is performed. Decision Tree Maker & Analyzer software calculates the sensitivity of all variables and display a sorted list based on the degree of sensitivity. Learn More

Diverse payoff info with multiple objectives and criteria

The decision tree software is capable of capturing multiple objective / multiple criteria in a rich format like boolean, subjective, numerical, monetary, etc. Learn More
Multi Criteria Decision Analysis

Rich math expression editor for Multi-Criteria Utility Function and Monte Carlo Simulation

Drag and drop criteria to the expression editor, and use a mathematical operator and built-in functions to form your custom expression. You will love this editor when you will need to perform a Monte Carlo simulation of your Random Function. Learn More

Use Probability Distribution as a payoff

A rich probability distribution modeling tool is within your reach. Incorporate a probability distribution as a payoff on any action or event node. Learn More
Probability Distribution

Perform Monte Carlo Simulation by incorporating a Probability Distribution

Model an uncertain payoff using the built-in advanced probability distribution modeling tool. Monte Carlo simulation is performed whenever a probability distribution is detected. A Risk profile is generated based on the Monte Carlo simulation. Learn More

Infer the risks in any situation

Get an array of risk metrics and charts from your decision tree. Look before you leap.
Risk metrics and charts

Every chart can be viewed as a data table or exported to Excel, and more...

For any chart you see in this application, right-click on your mouse to bring the context menu. You will find options for viewing the chart data as a data table or exporting the chart data to Excel. You will be able to copy the chart data as a CSV file in the clipboard. Also, you will be able to copy the chart image to the clipboard.

Update beliefs by experimentation using Bayesian Inference

Some uncertainties are highly sensitive, and you don't want to guess the probabilities. Experiment and incorporate your observations into your hypothesis updating process. A built-in Bayesian Inference tool is right there for you. Learn More
Bayesian Inference

Incorporate your attitude towards risk

You can be a realist, opportunist, risk-taker, or risk-averse. Choose your attitude towards risk and the Decision Tree software will calculate the best option for you accordingly.
