Let X = (Xn)n ∈ N0 be a homogenous Markov Chain with starting distribution μ and transition matrix P, where P(x, x) < 1 for all x ∈ S and. τ0: = 0 and τk + 1: = inf {n ≥ τk: Xn ≠ Xτk}(k ∈ N0). How can I show with the strong Markov Property that the sequence Y = (Yk)k ∈ N0 with Yk: = Xτk(k ... Webthe global and pairwise Markov properties (w.r.t.

Webof causal Markov properties and the de nition of graphical time series models is given in Section 3. The interpretation of mixed graphs associated with these models is enhanced by so-called global Markov properties which relate certain separation properties of the graph to conditional independence or Granger-noncausality rela-tions.
