edge_strength: Strength of edges in a Bayesian network
Description
Computation of the measure of edge strength for all edges in a Bayesian networks
Usage
edge_strength(bnfit)
Value
A dataframe with first two columns the edge list of the bn.fit input object. The third column Edge.Strength reports the measure of edge strength.
Arguments
bnfit
object of class bn.fit.
Details
The measure of edge strength is defined as the largest diameter out of all conditional probability tables where all other parents but the considered one are fixed to a specific combination.
