WebDefinition 11.4 (Time Homogeneous Markov Chains) . A Markov chain is time homogeneous if Pr[ X t+1 = s t+1 X t = s t] is independent of t, and in that case p i,j = Pr[ X t+1 = i X t = j] is well defined. Remarks: •We will only consider time homogeneous Markov chains. •Markov chains are often modeled using directed graphs, as in Fig-ure 11.1. WebThe chain graph Markov property. M. Frydenberg. Published 1990. Mathematics. Scandinavian Journal of Statistics. A new class of graphs, chain graphs, suitable for modelling conditional independencies are introduced and their Markov properties investigated. This class of graphs, which includes the undirected and directed acyclic …
Websummary graphs—which include ancestral graphs as well as chain graphs with the multivariate regression Markov property [2]—chain graphs with the LWF Markov property [9, 18], and chain graphs with the AMP Markov property [1]. In addition to the unification of the (global) Markov property, we provide a uni-fied pairwise Markov property.
