Moralize a DAG

Moralizing a DAG involves connecting all parents of each node and then converting all directed edges into undirected edges.

Usage

moralize(cg)

Arguments

cg

A caugi object (DAG).

Value

A caugi object representing the moralized graph (UG).

Details

This changes the graph from a Directed Acyclic Graph (DAG) to an Undirected Graph (UG), also known as a Markov Graph.

Examples

cg <- caugi(A %-->% C, B %-->% C, class = "DAG")
moralize(cg) # A -- B, A -- C, B -- C
#> <caugi object; 3 nodes, 3 edges; simple: TRUE; session=0x555e33c93570>
#>   graph_class: UG
#>   nodes: A, B, C
#>   edges: A---B, A---C, B---C
