Class Icon

BayesiaLab allows you to manage nodes as members of classes. Whenever any node is a member of any Class, an indicator icon appears in the Status Bar. By left-clicking the icon, you open the Class Editor; by right-clicking, you bring up a list of all Classes.

A class is a formal grouping of nodes. Certain classes are predefined in BayesiaLab, e.g., the classes Factor, Manifest, Non_Confounder, etc.; membership in such classes carries a specific meaning for inference and analysis. Beyond the predefined classes, you can group nodes together in a class and assign a name of your choice, which can help you organize and manage nodes in the Graph Window.

Selecting Classes

By default, all checkboxes are ticked, meaning that all Classes are visible in the Graph Window. By unchecking, you can “gray out” a class from the current display, i.e., the corresponding nodes and arcs now appear as semi-transparent in the Graph Window. Also, if a Class is unchecked, neither the nodes in that particular Class nor the arcs connecting to them can be manipulated in the Graph Window. The checkbox All allows you to quickly check and uncheck all classes in the list, and at the bottom of the list is a drop-down that allows you to define a Class Filter.
