Presented by Michael J. A. Berry or Gordon S. Linoff, founders of Data Miners, Inc. and co-authors of Data Mining Techniques and Mastering Data Mining
This course introduces survival analysis in the context of business data mining. The focus is on understanding customer behaviors that have a time-to-event component using SAS Enterprise Guide.
Learn how to
- identify appropriate opportunities for applying survival analysis techniques
- estimate how long a customer will remain active
- measure competing risks in survival analysis modeling.
Who should attend
Business analysts and managers, programmers, and statisticians

Prerequisites
There are no formal prerequisites. A background in business analysis, statistics, or mathematics is helpful but is not essential. The class exercises utilize SAS Enterprise Guide and some programming code is shown. Familiarity with SAS Enterprise Guide or with SAS programming is not required.
