Continuous Chance Node
======================

A continuous chance node (or CG node = continuous Gaussian node) represents a random variable with a :ref:`Gaussian (normal) conditional distribution function<gaussian_distribution_function>`. A continuous chance node can be added to the current network by activating the :ref:`continuous chance tool<Continuous_Chance_Tool>` and clicking somewhere in the :ref:`network pane<network_pane>`.

Currently, there are some restrictions to the use of continuous chance nodes, partly because the underlying theory is still being developed. The restrictions are listed below: 

* The only continuous chance nodes currently supported represent variables with Gaussian (normal) distribution functions. 
* A continuous chance node cannot be parent of a :ref:`discrete chance node<discrete_chance_node>`. 
* Continuous nodes cannot be used in influence diagrams. That is, continuous nodes cannot exist in a network also containing :ref:`utility nodes<utility_node>` or :ref:`decision nodes<decision_node>`.
