Absorb NodeΒΆ

A discrete chance node of a Bayesian network or a LIMID can be absorbed. The absorb node function can be activated in the Edit Menu.

A discrete chance node is absorbed by reversing all arcs emerging from A using the Arc Reversal operation.

As node absorption proceeds by a sequence of arc-reversal operations, new links may be added in the process. New links are added in order to maintain the conditional independence and dependence statements encoded in the network with respect to the unabsorbed variables.

Once all links emerging from A have been reversed, they are removed from the network. This completes the absorption of A. The node A is not deleted from the network.
