Invert Orientation Within the Equivalence Class
Context
In Validation Mode, you can only invert an arc if the inversion leads to an equivalent graph, i.e., a graph belonging to an Equivalence Class. All graphs in an Equivalence Class represent the same joint probability distribution.
Usage
- Select one or more arcs.
Arc Context Menu > Invert Arcs within the Equivalence Class.- If the proposed inversion produces a graph in the Equivalence Class, BayesiaLab automatically modifies the associated probability tables so that the joint probability distribution of the network graph remains unchanged.
- If the requested inversion does not generate a graph in the Equivalence Class, the arc direction remains unchanged.
