SAS/OR Software
Comprehensive Tools for Decision Analysis
The DTREE procedure is an interactive procedure for decision analysis. The procedure interprets a decision problem represented in SAS data sets, finds the optimal decisions, and plots on a line printer or a graphics device the decision tree showing the optimal decisions.
Input Data
-
The Stage data set contains the structure of the decision problem.
-
The Probability data set contains the discrete probability distributions on chance nodes.
-
The Payoff data set contains the returns on decision and chance nodes.
Output Data
- The Imagemap data set contains the outline coordinates for the nodes in the decision tree that can be used to generate HTML MAP tags.
Features
-
Automatically analyze the decision problem and display the decision tree on the line-printer or graphical device.
-
Calculate the value of perfect control and the value of perfect information.
- Incorporate decision maker's attitudes toward risk.
Interactive Features
-

-
Modify the decision model for sensitivity analysis.
