Based on Mutual Information, Relative Mutual Information is defined as:

In older versions of BayesiaLab, Relative Mutual Information was also called Normalized Mutual Information.

Please see the up-to-date definition of Normalized Mutual Information.


  • BayesiaLab reports the Relative Mutual Information in the Target Analysis Report: Main Menu > Analysis > Report > Target > Relationship with Target Node.

  • Note that this table shows the Relative Mutual Information of each node, e.g., XRay, Dyspnea, etc., only with regard to the Target Node, Cancer.

  • Note that the corresponding options under Preferences > Analysis > Visual Analysis > Arc's Mutual Information Analysis have to be selected first:

  • In Preferences, Child refers to the Relative Mutual Information from the Parent onto the Child node, i.e., in the direction of the arc.

  • Conversely, Parent refers to the Relative Mutual Information from the Child onto the Parent node, i.e., in the opposite direction of the arc.
