Web1 May 2024 · The Markov model classes we will review associate conditional independences in random vectors X=(X1,…,Xp)twith undirected graph and acyclic digraph separation properties. This is made explicit via the Markov propertiesof the distribution of X, which are in turn based on what are known as independence relations.
