Circularly - Coupled Markov Chain

I show how to run an N-time-step Markov chain simulation in a circular fashion, so that the state at time 0 follows the state at time N ?1 in the same way as states at times t follow those at times t?1 for 0 < t < N. This wrap-around of the chain is achieved using a coupling procedure, and produces states that all have close to the equilibrium distribution of the Markov chain, under the assumpt...

Conditioning properties of the stationary distribution for a Markov chain

Let T be an irreducible stochastic matrix with stationary vector πT . The conditioning of πT under perturbation of T is discussed by providing an attainable upper bound on the absolute value of the derivative of each entry in πT with respect to a given perturbation matrix. Connections are made with an existing condition number for πT , and the results are applied to the class of Markov chains a...

Reviving the Two-state Markov Chain Approach.

Probabilistic Boolean networks (PBNs) is a well-established computational framework for modelling biological systems. The steady-state dynamics of PBNs is of crucial importance in the study of such systems. However, for large PBNs, which often arise in systems biology, obtaining the steady-state distribution poses a significant challenge. In this paper, we revive the two-state Markov chain appr...

Ela a Combinatorial Approach to the Conditioning of a Single Entry in the Stationary Distribution for a Markov Chain∗

For an irreducible stochastic matrix T of order n, a certain condition number κj(T ) that measures the sensitivity of the j−th entry of the corresponding stationary distribution under perturbation of T is considered. A lower bound on κj is produced in terms of the directed graph of T , and the case of equality is characterized in that lower bound. Also all of the directed graphs D are character...
