# Discrete Function Node

The table of a discrete function node is not a conditional distribution given the parents (unlike the other discrete nodes). Instead, it is a marginal distribution which can be a function of the values of the parents.

Add a Discrete Function node by using the Discrete Function Tool.

The Discrete Function node table is specified using an expression in the node model.
