Because you do not deserve a poorly designed, boring and awkward user interface for Decision Analysis, SpiceLogic has brought to you the most intuitive and beautiful wizard-like Decision Analysis software. Enter Rational Will and never regret a Decision Again. An integrated Decision Analysis software featured with Decision Tree, Analytic Hierarchy Process, Decision Matrix, Markov Decision Process and more. • Just model a decision problem and behold a plethora of metrics and charts with Risk Profiles, Value of Information, Stochastic Dominance graph, Sensitivity Analysis, and Monte Carlo Simulation are done for you. Rich and comprehensive reports are generated with details. • Make smart decisions by looking at your decision problem from various angles. Reveal hidden factors by analyzing useful metrics, charts, and diagrams. • Know which action to take during which situation. Based on your attitude, evaluate policy by selecting a Decision Criterion like Maximize Expected Utility, Minimax Regret, Maximin, Hurwicz Optimism Pessimism Rule, etc. • Using Rational Will, be in charge of your life. Identify your objectives and options. Recognize what really matters. See the spectrum of 'things can happen' thru exhaustive sensitivity analysis. Be aware of your risks. Make rational decisions on everyday problems. • Model Rewards at an option or an event with Multiple-criteria Utilities. Rational Will Objectives can encapsulate rich information, like the attribute type of the objective. For example, some attributes can be Boolean Type (yes/no or true/false), some of them can be a Subjective type, Number type, or Categorical. Monetary type objective can be used to calculate Net Present Value using an interest rate. • When you have a probability distribution, Monte Carlo Simulation is performed automatically without asking you anything to configure. Whenever you have uncertainty, the Risk Profile chart is generated for you to visualize the complete possibilities of uncertain events and realize what can go wrong. Get prepared accordingly. • Realize the risks in any action you take. Observe a plethora of risk metric charts including Value at Risk, Entropy, Baumol's Risk measure, Domar and Musgrave Risk Index, Roy's safety first rule, Shortfall VaR, Variance, Standard Deviation, etc. • Try the analytic hierarchy process feature, and you will be amazed. The advanced guided wizard user interface is offered to model the Analytic Hierarchy Process. Rational will uses Eigenvalues and eigenvectors for calculating priorities from Pairwise Comparisons. • The Rational Will computes a strategy based on your Attitude. If you acknowledge as a realist rational person, the Von Neumann–Morgenstern utility theorem - Maximize Expected Utility approach will be used. If you are a very pessimist person who wants to avoid all kind of risks, you can choose LexiMin approach. If you regret opportunities, then the Minimax Regret approach is available for you. Hurwicz’s Optimism Pessimism rule is also available along with various customizations. • If you are not sure about your utility function, a Certainty Equivalent based Game can be offered to you. While you play the game, the 'Rational Will' will infer your Utility Function using the concept from Behavioral Economics. • Whenever you model uncertainty, you can update your beliefs based on experimentation and observations. A built-in Bayesian Inference tool called Diachronic Interpretation is ready for you to help you elicit the probabilities whenever you need. • When you compare random variables, Stochastic Dominance measure should be considered to rank the variables. 'Rational Will' can calculate Stochastic Dominance up to the 3rd Order. Whenever a model contains Uncertainty, the stochastic dominance is calculated in the Result Panel. •• TRY THE TRIAL VERSION TODAY •• The Trial version is a 7 day fully functional trial version. After 7 days, the application will stop working. You can purchase a license from Microsoft Store to continue beyond the Trial Period.
