Description

Check M-Identifiability.

Usage

mID(lambda, maxCard = length(observedNodes))

Arguments

lambda	adjacency matrix with number of cols = number of latent nodes, number of rows = number of observed nodes
maxCard	(optional) maximum size of set W

Value

a list consisting of a Boolean, whether the graph is sign-identifiable and if yes, a list consisting of the sets
