In Validation Mode, you can only invert an arc when 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 does produce 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.
