– 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

Examples of generali A Markov process is a random process indexed by time, and with the property that the future is independent of the past, given the present. Markov processes, named for Andrei Markov, are among the most important of all random processes.

Discrete-valued means that the state space of possible values of the Markov chain is finite or countable. A Markov process is basically a stochastic process in which the past history of the process is irrelevant if you know the current system state. Markov property will imply that the jump times, as opposed to simply being integers as in the discrete time setting, will be exponentially distributed. 6.1 Construction and Basic Definitions We wish to construct a continuous time process on some countable state space S that satisfies the Markov property. That is, letting F A discrete-state Markov process is called a Markov chain. Similarly, with respect to time, a Markov process can be either a discrete-time Markov process or a continuous-time Markov process. Thus, there are four basic types of Markov processes: 1.

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 these lecture series weIn these lecture series we consider Markov chains inMarkov chains in discrete time. Recall the DNA example.

(note Xi means X(ti)) A discrete time parameter, discrete state space stochastic process possessing Markov property is called a discrete parameter Markov chain (DTMC). Similarly, we can have other two Markov processes. Update 2017-03-09: Every independent increment process is a Markov process.
