Data Mining Techniques: Theory and Practice

Duration: 3.0 days CEUs: 1.8
Available for on-site training or can be scheduled at any SAS training facility if demand warrants.

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

Explore the inner workings of data mining techniques and how to make them work for you. Students are taken through all the steps of a data mining project, beginning with problem definition and data selection, and continuing through data exploration, data transformation, sampling, portioning, modeling, and assessment.

Learn how to

use a data mining methodology
build and use decision trees and neural networks for modeling and scoring
use survival analysis and create survival curves.

Who should attend

Business analysts, their managers, and statisticians
