RepMarBG
determines whether a given maximal ancestral graph can
be Markov equivalent to a bidirected graph, and if that is the case, it finds
a bidirected graph that is Markov equivalent to the given graph.
RepMarBG(amat)

An adjacency matrix, or a graph that can be a |
RepMarBG
looks for presence of an unshielded non-collider
V-configuration in graph.
A list with two components: verify
and
amat
. verify
is a logical value, TRUE
if there is
a representational Markov equivalence and FALSE
otherwise.
amat
is either NA
if verify == FALSE
or
the adjacency matrix of the generated graph, if
verify == TRUE
. In this case it consists of 4 different
integers as an ij
-element: 0 for a missing
edge between i
and j
, 1 for an arrow from i
to j
, 10 for a full line between
i
and j
, and 100 for a bi-directed arrow between i
and j
. These numbers are
added to be associated with multiple edges of different types. The matrix is
symmetric w.r.t full lines and bi-directed arrows.
