- [Instructor] Let's take a look at the SPSS Modeler interface. Modeler's all about building Streams. Here's an example of a Stream that builds to Decision Trees and we draw these Streams on the canvas and down at the bottom, there's a whole collection of these different shapes called Nodes that we use to build the Streams. So let's take a closer look at modeling, and especially classification. IBM® SPSS® Decision Trees enables you to identify groups, discover relationships between them and predict future events. It features highly visual classification and decision trees to help you present categorical results and more clearly explain analysis to non-technical audiences. IBM SPSS Decision Trees helps you better identify groups, discover relationships between them and predict future events through the exploration of results and visual determination of how your model flows. Create visual classification and decision trees directly within the Statistics suite of products and present results in an intuitive manner.

The Decision Tree procedure creates a tree-based classification model. It classifies cases into groups or predicts values of a dependent (target) variable based on values of independent (predictor) variables. The procedure provides validation tools for exploratory and confirmatory classification analysis. The purpose of decision trees is to model a series of events and look at how it affects an outcome. This type of model calculates a set of conditional probabilities based on different scenarios.
