• Run, open and save a stream.
• Access the help function within Modeler.

Data Mining Tour

• Explain the primary concepts used in data mining.
• Build, evaluate and deploy a model.
• Use the Sort and Filter nodes.

Collecting Initial Data

• Explain the concepts of "data structure", "records", "fields", "unit of analysis", "storage".
• Read data from and export data to various file formats

Data Understanding

• Examine the distributions of categorical and continuous fields.
• Explain the most common ways of handling missing data.

• Aggregate data.
• Create flag fields.
• Restructure continuous fields.

Integrating Data

• Add records from multiple datasets into one dataset.
• Add fields from multiple datasets into one dataset.
• Use sampling for testing purposes.

Deriving and Filling Fields

• Use CLEM to transform data.
• Use the Derive node to create a new field, and the Filler node to replace values in a field.
• Explain how to automatically generate a Derive node.
• Use the Reorder node to reorder fields.

Reclassifying and Binning Fields

• Use the Reclassify node.
• Explain how to automatically generate a Reclassify node.
• Use the Binning node.

Looking for Relationships

• Examine the relationship between two categorical fields.

Introduction to Classification

• Differentiate between predictive modeling and other types of modeling.
• Differentiate between various types of predictive models.
• Run CHAID in interactive mode.
• Run CHAID and various other models in automatic mode.
