An EM Algorithm for Continuous-time Bivariate Markov Chains
Parameter estimation EM algorithm Continuous-time bivariate Markov chain
2011/7/19
We study properties and parameter estimation of finite-state homogeneous continuous-time bivariate Markov chains.
Bayesian analysis of variable-order, reversible Markov chains
Reversibility reinforced random walks variable-order Markov chains Bayesian analysis conjugate priors
2011/6/17
We define a conjugate prior for the reversible Markov chain of
order r. The prior arises from a partially exchangeable reinforced
random walk, in the same way that the Beta distribution arises from

Regenerative block empirical likelihood for Markov chains
Nummelin splitting technique time series Empirical Likelihood MSC codes: 62G05 62F35 62F40
2011/3/23
Empirical likelihood is a powerful semi-parametric method increasingly investigated in the literature. However, most authors essentially focus on an i.i.d. setting. In the case of dependent data, the ...

2011/3/25
For a Markov transition kernel $P$ and a probability distribution $ \mu$ on nonnegative integers, a time-sampled Markov chain evolves according to the transition kernel $P_{\mu} = \sum_k \mu(k)P^k.$ I...
In this paper, we relate the coupling of Markov chains, at the basis of perfect sampling methods, with damage spreading, which captures the chaotic nature of stochastic dynamics. For two-dimensional ...
Geometric ergodicity for families of homogeneous Markov chains
Homogeneous Markov chain Geometric ergodicity Couplingrenewal processes Lyapunov function Renewal theory
2010/3/11
In this paper we find nonasymptotic exponential upper bounds for
the deviation in the ergodic theorem for families of homogeneous Markov
processes. We find some sufficient conditions for geometric e...
Invariant measures and Markov chains with random transition probabilities
Invariant measures Markov chains random transition probabilities
2009/9/22
In this paper, suTTicient conditions for the existence of
(a-finite) invariant measures for a class of Markov chains with random
transition probabilities are given. A special class of Markov chains

We consider stationary homogeneous Markov chains
and the polygonal processes defined by a usual way using such chains.
There are many results about invariance principles of those processes.
In this...

Moderak deviations Markov chains geometric ergodicity regeneration split chain method
2009/9/22
We obtain uniform (in time) moderate deviations for
the functional empirical process ofa general state space Markov chain
under the geometric ergodicity assumption, and a regularity condition

This paper surveys various results about Markov chains on general (non-countable) state spaces. It begins with an introduction to Markov chain Monte Carlo (MCMC) algorithms, which provide the motivati...

Differential equation Markov chains
2009/5/18
We formulate some simple conditions under which a Markov chain may be approximated by the solution to a differential equation, with quantifiable error probabilities. The role of a choice of coordinate...
Various notions of geometric ergodicity for Markov chains on general state spaces exist. In this paper, we review certain relations and implications among them. We then apply these results to a collec...

2009/5/4
This paper provides transition probability estimates of transient reversible Markov chains. The key condition of the result is the spatial symmetry and polynomial decay of the Green's function of the ...

2009/4/29
We state and prove a simple quantitative bound on the total variation distance after k iterations between two Markov chains with different initial distributions but identical transition probabilities....

We consider a ψ-irreducible, discrete-time Markov chain on a general state space with transition kernel P. Under suitable conditions on the chain, kernels can be treated as bounded linear operators...
