Equations

Equations

The relationship between a node and its parent nodes can be entered using an equation if desired.  This is possible whether the nodes are continuous or discrete, and whether the relationship is probabilistic or deterministic.  Netica will convert all equations into tables (= 4 && typeof(BSPSPopupOnMouseOver) == 'function') BSPSPopupOnMouseOver(event);" class="BSSCPopup" onclick="BSSCPopup('X_PU_CPT.htm');return false;">CPT or = 4 && typeof(BSPSPopupOnMouseOver) == 'function') BSPSPopupOnMouseOver(event);" class="BSSCPopup" onclick="BSSCPopup('X_PU_function_table.htm');return false;">function table) before compiling a net, doing net transforms, or expanding a DBN.  The tables are then used in the same way as if you had entered them by hand.
