Recall that a Markov chain is a discrete-time process {X n; n 0} for which the state at each time n 1 is an integer-valued random variable (rv) that is statistically dependent on X 0,X n1 only through X n1. A countable-state Markov process1 (Markov process for short) is a generalization of a Markov chain in the sense that, along with the Markov

Keywords: Semi-Markov processes, discrete-time chains, discrete fractional operators, time change, fractional Bernoulli process, sibuya counting process.

A Markov chain is a type of Markov process that has either discrete state space or discrete index set. It is common to define a Markov chain as approximation of the Markov decision process. We give bounds on the difference of the rewards and an algorithm for deriving an approximating solution to the Markov decision process from a solution of the HJB equations. We illustrate the method on three examples pertaining, respectively, Just as with discrete time, a continuous-time stochastic process is a Markov process if the conditional probability of a future event given the present state and additional information about past states depends only on the present state. A CTMC is a continuous-time Markov vector, then the AR(p) scalar process can be written equivalently as a vector AR(1) process..

1. Introduction. Given some probability space, it is often challenging to  Solution. We first form a Markov chain with state space S = {H, D, Y } and the following transition probability matrix : P  Continuization of discrete time chain. Let (Yn)n≥0 be a time-homogeneous Markov chain on S with transition functions p(x, dy),. Xt = YNt , Nt Poisson(1)- process  is a discrete-time Markov chain, with one-step transition probabilities p∆(x, y).

When T = N and the state space is discrete, Markov processes are known as discrete-time Markov chains. The theory of such processes is mathematically elegant and complete, and is understandable with minimal reliance on measure theory. Indeed, the main tools are basic probability and linear algebra.

Update 2017-03-09: Every independent increment process is a Markov process. FOYa discrete-state discrete-transition Markov process we may use the Marliov condition on the right-hand side of this equation to obtain which may be substituted in the above equation for pij(k) to obtain the result This relation is a simple case of the Chapman-Kolmogorov equation, and it may be used as an alternative definition for the discrete-state discrete-transition Aiarkov process with constant transition proba- bilities.

– Homogeneous Markov process: the probability of state change is unchanged by time shift, depends only on the time interval P(X(t n+1)=j | X(t n)=i) = p ij (t n+1-t n) • Markov chain: if the state space is discrete – A homogeneous Markov chain can be represented by a graph: •States: nodes •State changes: edges 0 1 M

Figure B.1: Graphical model illustrating an AR(2) process. Moving from the discrete time to the continuous time setting, the question arises as to how generalize the Markov notion used in the discrete-time AR process to define a continuoous Markov processes A Markov process is called a Markov chain if the state space is discrete i e is finite or countablespace is discrete, i.e., is finite or countable.

In Chapter 3, we considered stochastic processes that were discrete in both chains is simply a discrete time Markov chain in which transitions can happen at  

Discrete-time Markov chain (or discrete-time discrete-state Markov process) 2. Continuous-time Markov chain (or continuous-time discrete-state Markov process) 3. A Markov chain is a Markov process with discrete time and discrete state space. So, a Markov chain is a discrete sequence of states, each drawn from a discrete state space (finite or not), and that follows the Markov property.
