Managing grouping options for numeric predictors manually
Combine values or ranges based on the similarity of numeric predictor behavior.
- In the Data analysis step, click a numeric predictor.
- In the predictor workspace, click the Grouping tab.
field, enter the maximum probability of
spurious difference in behavior.
Reducing this probability reduces interval or category numbers.
Minimum size (% of samples)
field, specify the minimum
number of cases in each interval or category. Click
This option ensures 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.
- Optional: To read the data in a graph or a table, click the Graphical view tab or the Tabular view tab
- Confirm your updates by clicking Submit.
