Managing grouping options for numeric predictors manually

Combine values or ranges based on the similarity of numeric predictors' behavior.

You can use the Auto grouping option and enable the Analytics Center portal to group predictors automatically.

1. In the Data analysis step, click a numeric predictor.

2. Click the Grouping tab.

3. In the Granularity field, specify the maximum probability of spurious difference in behavior.

   Reducing this probability reduces interval or category numbers.

4. In the Minimum size (% of samples) field, specify the minimum number of cases in each interval or category.

   Use this option to ensure that the behavior evidence is sufficient to be used in grouping. Intervals with few cases are combined with their nearest neighbor. Categories with few cases are combined into a residual bin.

5. Click Apply.
6. Optional: Click the Graphical view tab or Tabular view tab to read the data in the graph or table.
7. Optional: If you change the field properties, you can select theUse as default settings option to override the default project settings.
8. Click Submit.
