Test Node Input

A Test node has the following input:

• At least one node that identifies one or more models. The nodes can be a Model node, a Classification node, or a Regression node. A Model node must contain either Classification or Regression model, but not both.

• Any node that generates data as an output such as a Data node, a Transform node, or an appropriate Text node. This node contains the test data.

• It is recommended that a case ID is specified. If you do not specify a Case ID, then the processing will take longer.

You can test several Classification or several Regression Models at the same time. The models to be tested can be in different nodes. The models to be tested must satisfy these conditions:

• The nodes that contain the models must have the same function type. That is, they must be all Classification Build nodes or all Regression Build nodes.

  Classification Models must also have the same list of target attribute values.

• The models must have the same target attribute with the same data type.

• The Data Source node for Test must contain the target of the models.

• The test data must be compatible with the models. That is, it should have been transformed in the same way as the data used to build the model.
