opd: Get the ordered power DAG

In rje42/ADMGs2: Functions for Describing and Fitting Discrete Mixed Graphs

Get the ordered power DAG

Description

Returns the ordered power DAG for an ordinary Markov ADMG

Usage

opd(graph, topOrd, v, include_empty = FALSE)

Arguments

graph	an ADMG of class mixedgraph
topOrd	a topological ordering of the vertices in graph
v	optionally the vertices to obtain components for
include_empty	logical: should independences be included even if there are no variables in one set?

Details

Returns the ordered power DAG, as defined in Hu and Evans (2022), giving independences implied by the local Markov property and sufficient to define the model.
