Decision Tree Analysis

Decision trees are widely used in operations research. It is mostly applied in decision analysis in order to help and identify that strategy that most likely may lead to reaching a goal. It is also known as a popular tool in machine learning, thus it worth knowing about it from this article.

The ConceptDraw DIAGRAM diagramming and drawing software is the one that can help with creating the needed drawing, including a decision tree. Making decision tree analysis, it is always easy to make the needed matrix as there are plenty of pre-made templates to be used.

This example was designed on the base of Figure 4.33 "Decision Tree Comparing Colorectal Screening Current Practice with a Targeted Family History Strategy" from the "Principles of Epidemiology in Public Health Practice, Third Edition. An Introduction to Applied Epidemiology and Biostatistics. Self-Study Course SS1978. Lesson 4: Displaying Public Health Data. Section 4: Other Data Displays" on the Centers for Disease Control and Prevention (CDC) website.
"The graph shows a decision tree with outcomes, and probabilities. In this case, a family history decision tree has 16 potential outcomes."

"A decision tree is a decision support tool that uses a tree-like graph or model of decisions and their possible consequences, including chance event outcomes, resource costs, and utility. It is one way to display an algorithm that only contains conditional control statements.
Decision trees are commonly used in operations research, specifically in decision analysis, to help identify a strategy most likely to reach a goal, but are also a popular tool in machine learning." [Decision tree. Wikipedia]

"A decision tree is a flowchart-like structure in which each internal node represents a "test" on an attribute (e.g. whether a coin flip comes up heads or tails), each branch represents the outcome of the test, and each leaf node represents a class label (decision taken after computing all attributes). The paths from root to leaf represent classification rules." [Decision tree. Wikipedia]

In decision analysis a decision tree and the closely related influence diagram is used as a visual and analytical decision support tool, where the expected values (or expected utility) of competing alternatives are calculated.
A decision tree consists of 3 types of nodes:
(1) Decision nodes - commonly represented by squares.
(2) Chance nodes - represented by circles.
(3) End nodes - represented by triangles.
