Home > Model Nodes > Model Nodes Property Inspector > Test
This tab is displayed for Classification and Regression models; they are the only kinds of models that can be tested.
The test tab defines how tests are done. The default is to test all models built.
These are the ways to test classification and regression models:
The default is to randomly split the input data into build data and test data.
By default, 40% if the input data is used for the test set. You can change the percent, or you can also use all of the build data for testing.
You can use all of the build data as test data.
Attach two data source nodes to the build node. The first data source that you connect to the build node is the source of build data; the second node that you connect is the source of test data.
Unselect Perform Test on the test tab and use a Test Node.
Testing is not required; you can unselect Perform Test and not test at all.
See Create Classification Node or Create Regression Node for details.
