Markov Blanket

The markov blanket for a node can be displayed by selecting the node and then click the Show Markov Blanket option in the the d-separation pane.

The Markov Blanket of a node A is the set consisting of the the parents of A, the children of A, and the nodes sharing a child with A.

If all variables in the Markov blanket for A are instantiated, then A is d-separated from the rest of the network.

For example the markov blanket for the node I in Figure 1 is {C, E, H, K, L}, which can be seen in Figure 2.
