In SAS^® Enterprise Miner™, the Model Comparison node Selection Statistic property value you choose might be ignored when the node selects a model. The node might select an incorrect model when you have a Data Partition node in your flow, or when you specify your own validation and test data sets.

There are no warnings or errors to indicate that the incorrect model was chosen.

In order to determine whether or not the problem occurred, examine the results and compare the "Model selection based on" Fit Statistic value to the Selection Statistic property value you chose. If they do not match, the problem occurred — the node did not select the correct model.

If an incorrect model was selected, you can work around the problem by manually adding a line from the correct model node to any succeeding nodes.

Additional information depends on whether or not a decision matrix is created.

If a decision matrix is created, the following Selection Statistic property values will cause the problem:

• Default
• Valid: Captured Response
• Valid: Gain
• Valid: Lift
• Valid: Percent Response

If a decision matrix is not created, the following Selection Statistic property values will cause the problem:

• Default
• Valid: Captured Response
• Valid: Gain
• Valid: Lift
• Valid: Average Profit/Loss
• Valid: Percent Response
