Organizing Data Selections

By organizing data selections (a mining dataset), you can specify which evaluation measures Decision List Viewer should analyze to find new rules and select which data selections are used as the basis for measures.

To organize data selections:

1. From the Tools menu, choose Organize Data Selections, or right-click a segment and choose the option. The Organize Data Selections dialog opens.

   Note: The Organize Data Selections dialog also enables you to edit or delete existing data selections.

2. Click the Add new data selection button. A new data selection entry is added to the existing table.
3. Click Name and enter an appropriate selection name.
4. Click Partition and select an appropriate partition type.
5. Click Condition and select an appropriate condition option. When Specify is selected, the Specify Selection Condition dialog opens, providing options for defining specific field conditions.
6. Define the appropriate condition and click OK.

The data selections are available from the Build Selection drop-down list in the Create/Edit Mining Task dialog. The list enables you to select which evaluation measure is used for a particular mining task.
