An introduction to Markov chains
web.math.ku.dkmodels for random events namely the class of Markov chains on a finite or countable state space. The state space is the set of possible values for the observations. Thus, for the example above the state space consists of two states: ill and ok. Below you will find an ex-ample of a Markov chain on a countably infinite state space, but first

There are three items involved: to specify a Markov chain, I need to tell you its •State space S. S is a finite or countable set of states, that is, values that the random variables Xi may take on.

www.stat.yale.edu2 1MarkovChains 1.1 Introduction This section introduces Markov chains and describes a few examples. A discrete-time stochastic process {X n: n ≥ 0} on a countable set S is a collection of S-valued random variables defined on a probability space (Ω,F,P).The Pis a probability measure on a family of events F (a σ-field) in an event-space Ω.1 The set Sis the state space of the …

If the state space is finite and all states communicate (that is, the Markov chain is irreducible) then in the long run, regardless of the initial condition, the Markov chain must settle into a steady state. Formally, Theorem 3. An irreducible Markov chain Xn on a finite state space n!1 n = g=ˇ( T T

www.statslab.cam.ac.ukSome Markov chains settle down to an equilibrium state and these are the next topic in the course. The material in this course will be essential if you plan to take any of the applicable courses in Part II. Learning outcomes By the end of this course, you should: • understand the notion of a discrete-time Markov chain and be familiar with both

As you might know, the countable infinity is one of many different infinities we encounter in mathematics. Simply, a set is countable
