Building the Stream

1. To build the stream, add a Statistics File source node pointing to telco.sav located in the Demos directory of your IBM® SPSS® Modeler installation.
   Figure 1. Building the stream

   
2. Attach a Type node to the source node, set the measurement level for the churn field to Flag, and set the role to Target. All other fields should have their role set to Input.
   Figure 2. Selecting the target

   
3. Attach a Logistic node to the Type node.
4. In the Logistic node, click the Model tab and select the Binomial procedure. In the Model name field, select Custom and enter No ADP - churn.

5. Attach an ADP node to the Type node. On the Objectives tab, leave the default settings in place to analyze and prepare your data by balancing both speed and accuracy.
6. At the top of the Objectives tab, click Analyze Data to analyze and process your data.

   Other options on the ADP node enable you to specify that you want to concentrate more on accuracy, more on the speed of processing, or to fine tune many of the data preparation processing steps.

   The results of the data processing are displayed on the Analysis tab. The Field Processing Summary shows that of the 41 data features brought in to the ADP node, 19 have been transformed to aid processing, and 3 have been discarded as unused.

7. Attach a Logistic node to the ADP node.
8. In the Logistic node, click the Model tab and select the Binomial procedure. In the Modeling name field, select Custom and enter After ADP - churn.
