Add Class

The simplest way to add a node to a Class is via the Node Contextual Menu.

• Select the nodes you wish to assign to a Class and then right-click on one of them.
• From the Contextual Menu, you then select Properties > Classes > Add.
• The Add Class Dialog Box offers you a choice regarding the Class:
  • Existing Class, if any are already associated with your network:
  • Predefined Class, which includes:
    • Factor
    • Manifest
    • Non_Confounder
    • Hyperparameter
    • Resource
    • Opt_Hard_Evidence
  • New Class

Example & Workflow Animation

For illustration purposes, we utilize a well-known diagnostic model for Coronary Artery Disease (see Diagnostic Decision Support).

In the following animation, we show how to add the nodes Q Wave and T Wave Inversion to the new ClassECG, as both nodes represent signals that can potentially be detected by performing an electrocardiogram (ECG).

Note that four other Classes have already been defined in this example, i.e., Demographic, Diagnosis, Laboratory and Echo, Symptoms and Examination, in addition to BayesiaLab's predefined Classes.
