Decision tree

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." [cdc.gov/ophss/csels/dsepd/ss1978/lesson4/section4.html] "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."
