Churn Case StudyAnalysis 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)
![Page 5: Chapter 3: SAS Rapid Predictive Modeler](https://reader035.fdocuments.us/reader035/viewer/2022081503/56813327550346895d9a1174/html5/thumbnails/5.jpg)

Churn Case Study: BasicsThroughout 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.
1. Import the CHURN_RPM data.
2. Build the SAS Rapid Predictive Modeler model in SAS Enterprise Guide.
3. Score the CHURN_RPM_SCORE data set.
4. Open the model in SAS Enterprise Miner.
5. Improve the model.

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 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.

Census Income Case StudyAnalysis Goal:
The goal is to develop a model to predict whether a person makes more than 50K a year based on census data.
Data set: ADULT
Number of rows: 32,562
Number of columns: 14
Contents: age, work class, education, marital status, race, sex,
capital gain or loss,hours worked, and so on
Targets: TARGET (binary)

Census Income Case Study: BasicsThis case study demonstrates how to invoke SAS Rapid Predictive Modeler from SAS Enterprise Guide and then open the generated project in SAS Enterprise Miner.
1. Import the ADULT data.
2. Build the SAS Rapid Predictive Modeler model in SAS Enterprise Guide.
3. Open the model in SAS Enterprise Miner.
4. Inspect the results.
