A decision node represents a decision to be made by the user. A decision node can be added to the current network by activating the Decision Tool and clicking somewhere in the Network Pane. A Bayesian network extended with decision nodes and utility nodes is called a Limited Memory Influence Diagram (LIMID). The decision nodes represent decisions controlled by an external user. This means that compared to discrete chance nodes, decision nodes have no conditional probability tables (CPTs). Instead an initial policy for the decision is specified.
Decision nodes cannot appear in a network together with continuous chance nodes.
Decision nodes are assigned a type.
