To use
the Model Comparison node to compare the models that you
have built in this example and to select one as the champion model,
complete the following steps:
-
Select
the
Utility tab on the Toolbar.
-
Select
the Control Point node icon. Drag the node into the Diagram
Workspace.
-
Connect
all five model nodes to the Control Point node.
Tip
Control Point
nodes enable you to better organize your process flow diagram. These
nodes do not perform calculations; they simply pass data from preceding
nodes to subsequent nodes.
-
Select
the
Assess tab on the Toolbar.
-
Select
the Model Comparison node icon. Drag the node into the Diagram Workspace.
-
Connect
the Control Point node to the Model Comparison node.
-
In the
Diagram Workspace, right-click the Model Comparison node, and select
Run from the resulting menu. Click
Yes in the confirmation window that opens.
-
In the
window that appears when processing completes, click
Results. The
Results window opens.
-
In the
Fit Statistics window, notice that the logistic regression
model was selected as the champion model. The champion model has the
value
Y
in the Selected Model column
in the
Fit Statistics window.
In the
model selection node, SAS Enterprise Miner selects the champion model
based on the value of a single statistic. You can specify which statistic
to use for selection in the node Properties Panel. Because you did
not change the value of this property, the default statistic was used,
which (because a profit matrix is defined) is average profit in the
validation data.

Close
the
Results window.
