Data mining with tree-based models

Classification of cases in groups is one of the most important tasks in data mining and analytics. In the previous recipe, Clustering, we made clusters of similar cases based on measures by letting Tableau discover groups and patterns in the data. However, there are also situations where we already have a dimension labeling certain groups in our data, and we want to create a model that will predict group membership using other fields in our dataset. For this task, we can use a tree-based model. By the end of this chapter, you'll have built a decision tree using a classification algorithm, while retaining a focus on a real-life business question.
