E N D
Objectives • Present a typical approach to data mining. • State the key business drivers of SAS Rapid Predictive Modeler. • Present an alternative approach to data mining where the business analyst and subject matter expert develops his or her own models. • Describe the key capabilities of SAS Rapid Predictive Modeler.
Churn Case Study Analysis Goal: A telecommunications company wants to decrease the number of churning customers through the development of a churn classification model. Data set: CHURN_RPM Number of rows: 4,708 Number of columns: 15 Contents: account information, call history, equipment and complaint history Targets: TARGET_CHURN (binary)
Churn Case Study: Basics • Throughout this chapter, you work with data in SAS Enterprise Guide and SAS Enterprise Miner to perform fast and accurate modeling with SAS Rapid Predictive Modeler. • Import the CHURN_RPM data. • Build the SAS Rapid Predictive Modeler model in SAS Enterprise Guide. • Score the CHURN_RPM_SCORE data set. • Open the model in SAS Enterprise Miner. • Improve the model.
Data Mining and Predictive AnalyticsConventional Approach Quantitative Modeler / Statistician • Model Development, Deployment, and Management • SAS Enterprise Miner, SAS/STAT • Apply model to specific customer issues (ex. find out customers, which are most likely to churn) • SAS Enterprise Guide, SAS Add-In for Microsoft Office Business Analyst / Subject Matter Expert • Data preparation and data cleansing • SAS Data Integration Studio Database Admin / IT
SAS Rapid Predictive ModelerKey Business Drivers • Need to generate numerous models to support a variety of business problems. • Models need to be developed in a short time-frame using a self-service approach. • Does not have to always rely on a statistician or modeler. • Collaborate to augment, validate, and deploy models.
SAS Rapid Predictive ModelerComplementary Approach • Generate predictive models in a quick, automated fashion • Easy-to-understand reports and charts • Register model in SAS metadata • SAS Enterprise Guide or SAS Add-In for Microsoft Office Business Analyst / Subject Matter Expert Quantitative Modeler / Statistician • Refine model and perform model comparison • Test, validate, and select champion model • Monitor model performance for degradation • SAS Enterprise Miner SAS, Model Manager • Data preparation and data cleansing • SAS Enterprise Data Integration Server Database Admin / IT
SAS Rapid Predictive ModelerPrimary Objectives • Generate predictive models quickly and accurately. • Provide self-sufficiency to business users. • Generate easy-to-understand charts and reports. • Integrate analytics and BI for better decisions.
SAS Rapid Predictive Modeler’s Target Customers • Across all industries • Those dealing with customer-oriented and marketing-analytics-oriented issues • Those who need to generate numerous models to support a variety of business problems: • customer acquisition • up-sell and cross-sell • customer retention • customer churn • Business analysts, subject matter experts, and business professionals with little to no statistical knowledge • Statisticians or data miners who need to develop quick baseline models that address common business issues
What Is SAS Rapid Predictive Modeler? • SAS Rapid Predictive Modeler is a customized task that runs prebuilt SAS Enterprise Miner models. • It is an add-in for SAS Enterprise Guide or SAS Add-In for Microsoft Office. • It requires SAS Enterprise Miner and is included in SAS Enterprise Miner packaging. • It also works with SAS Enterprise Miner for Desktop. • It enables business users, without prior statistical knowledge, to build predictive models quickly and effectively. • Results can be consumed in simple and easy-to-understand charts to make better decisions.
Key Capabilities • You choose from basic, intermediate, or advanced prebuilt methods. • SAS Rapid Predictive Modeler automatically handles outliers, missing values, rare target events, skewed data, variable selection, and model selection. • Analytic results are presented in easy-to-understand business terms: scorecard, lift charts, and listing of key variables in the model. • Analytic experts can further customize and improve models developed in SAS Rapid Predictive Modeler using SAS Enterprise Miner. • Models are registered in SAS metadata to • automate the execution of score code • ease deployment to other systems.
Objectives • Give an overview of the SAS Rapid Predictive Modeler process.
SAS Rapid Predictive Modeler Modeling Process: Overview Open SAS Enterprise Guide or Microsoft Excel. Invoke the SAS Rapid Predictive Modeler task. Select the data to model. Define modeling roles (done automatically if variables are aptly named – for example, target_churn). Run. Review results. (You can save and share them.) (optional) Save task to a SAS Enterprise Miner project. (optional) Register the model in SAS metadata.

Objectives • Demonstrate how SAS Enterprise Miner project data from an RPM model can be saved for later inspection and refinement.
SAS Rapid Predictive Modeler: Options Panel Save SAS Enterprise Miner project data from your SAS Rapid Predictive Modeler model.
Objectives • Show how a SAS Rapid Predictive Modeler model can be registered to the SAS Metadata Repository and explain why this might be necessary.
Register the SAS Rapid Predictive Modeler Model • Use Cases: • Import and score using the Model Scoring task in SAS Enterprise Guide. • Import into SAS Enterprise Miner using the Model Import node for integrated model comparison. • Import into SAS Model Manager for champion/challenger model management. • Import into SAS Data Integration Studio to score with mining results transformation. • Publish as a scoring function for Teradata, Netezza, or IBM DB2. Register the model to the SAS Metadata Repository.
