• To see the plot for another model, select the model from the Show list and click Query.

You can control how the plot is displayed in several ways:

• Select the information displayed on the y-axis and on the x-axis. The default depictions are:

  • X axis: Predicted Value

  • Y axis: Residual

  To change this, select information from the lists.

• The default sample size is 2000. You can make this value larger or smaller.

• You can compare plots side by side. The default is to not compare plots.

If you change any of these fields, then click Query to see the results.

To compare plots side by side, select the model to compare with the current model from the Compare list and click Query. The residual plots are displayed side by side.

The bottom pane show the Residual result summary table. The table contains the Models grid which supplements the information presented in the plots. You can minimize the table using the splitter line.

The table has the following columns:

• Model, the name of the model along with color of the model in the graphs

• Predictive Confidence

• Mean Absolute Error

• Root Mean Square Error

• Mean Predicted Value

• Mean Actual Value

• Algorithm

• Creation Date (and time)

By default, results for all models in the node are displayed. To change the list of models, click to open the Edit Test Selection (Classification and Regression) dialog box.
