Markov equivalence, ch. 5 p. 85 (Verma and Pearl, 1991)

Two DAGs are Markov equivalent iff they share a skeleton and a set of colliders.

Usage

morie_mectest(dag1, dag2)

Arguments

dag1, dag2

directed edge matrices

Value

list(equivalent, sameskeleton, samecolliders, nskeleton, ncolliders1, ncolliders2)

Examples

V <- c(1, 2, 3, 4, 5, 6, 7, 8)
morie_mectest(V, V)
