Predicted Error Data

If the model is imported from the Model Browser, it is possible to display the predicted error (PE) data.

The PE is the absolute error between the model and the data used to construct the model. The Model Browser compares the model and the original data, and stores the error between the model and the original data as the PE of the model.

Viewing the PE

Select Display PE from the right-click menu.

You can only view the PE if you are displaying one of the following:

• Surface
• Table

Surface Display of PE

• Where the error is greatest, the surface is red.
• Where the error is least, the surface is blue.

It is possible to see a scale for the PE by clicking PE Colorbar from the right-click menu.

Table Display of PE

The table shows all points that are beyond the PE threshold as being purple.

Setting the PE Threshold

To set the threshold of the PE display:

• Select Display Options -> Set PE Threshold.

• The Predicted Error Threshold dialog box appears.

• Select an appropriate value for the PE threshold and click OK.
