d-separation

The d-separation rule enables you to quickly determine whether a = 4 && typeof(BSPSPopupOnMouseOver) == 'function') BSPSPopupOnMouseOver(event);" class="BSSCPopup" onclick="BSSCPopup('X_PU_finding.htm');return false;">finding at one node can possibly change the = 4 && typeof(BSPSPopupOnMouseOver) == 'function') BSPSPopupOnMouseOver(event);" class="BSSCPopup" onclick="BSSCPopup('X_PU_belief.htm');return false;">beliefs at another by only looking at the = 4 && typeof(BSPSPopupOnMouseOver) == 'function') BSPSPopupOnMouseOver(event);" class="BSSCPopup" onclick="BSSCPopup('X_PU_link_structure.htm');return false;">link structure of a Bayes net.

Netica uses d-separation internally, and can also find and display d-separated nodes.
