QUEST Criteria

For the QUEST method, you can specify the significance level for splitting nodes. An independent variable cannot be used to split nodes unless the significance level is less than or equal to the specified value. The value must be greater than 0 and less than 1. The default is 0.05. Smaller values will tend to exclude more independent variables from the final model.

   Analyze > Classify > Tree...
