PDAG

Overview

class graphical_models.PDAG(nodes: Set = {}, arcs: Set = {}, edges: Set = {}, known_arcs={}, new=False)

Methods

PDAG.copy()	Return a copy of the graph
PDAG.to_amat([node_list, source_axis])	Return an adjacency matrix for the graph
PDAG.from_amat(amat[, source_axis])	Return a PDAG with arcs/edges given by amat

Graph modification

PDAG.remove_node(node)

Remove a node from the graph

Graph properties

PDAG.has_edge(i, j)	Return True if the graph contains the edge i--j
PDAG.has_edge_or_arc(i, j)	Return True if the graph contains the edge i--j or an arc i->j or i<-j

Comparison to other PDAGs

PDAG.shd(other)

Return the structural Hamming distance between this PDAG and another.

Functions for

PDAG.to_dag()	Return a DAG that is consistent with this CPDAG.
PDAG.all_dags([verbose])	Return all DAGs consistent with this PDAG
