used to nd the expected number of steps needed for a random walker to reach an absorbing state in a Markov chain. These methods are: solving a system of linear equations, using a transition matrix, and using a characteristic equation. Keywords: probability, expected value, absorbing Markov chains, transition matrix, state diagram 1 Expected Value

transition diagrams and First-Step Analysis. The processes can be written as {X0 ... Definition: The state of a Markov chain at time t is the value of Xt.

Starting from an any state, a Markov Chain visits a recurrent state infinitely many times, or not at all. Let us now compute, in two different ways, the expected number of visits to i (i.e., the times, including time 0, when the chain is at i). First we observe that at every visit to i, the probability of never visiting i again is 1 −fi ...

Can anyone give an example of a Markov Chain and how to calculate the expected number of steps to reach a particular state? Or the probability of reaching a particular state after T transitions? I ask because they seem like powerful concepts to know but I am having a hard time finding good information online that is easy to understand.

Apr 03, 2015 · Using the Markov Chain Markov chains are not designed to handle problems of infinite size, so I can't use it to find the nice elegant solution that I found in the previous example, but in finite state spaces, we can always find the expected number of steps required to reach an absorbing state. Let's solve the previous problem using \( n = 8 \).

The distribution for the number of time steps to move between marked states in a discrete time Markov chain is the discrete phase-type ...

Therefore expected number of steps of first reaching v from u=E(X) = p = n−1. 2. The expected number of steps starting from u to visit all the vertices in K n is (n − 1)H n−1, where H n−1 = P n−1 j=1 1/j is the Harmonic number. Solution: Let X be a random variable defined to be the number of steps required to visit all vertices in K ...

The distribution for the number of time steps to move between marked states in a discrete time Markov chain is the discrete phase-type distribution.You made a mistake in reorganising the row and column vectors and your transient matrix should be $$\mathbf{Q}= \begin{bmatrix} \frac{2}{3} & \frac{1}{3} & 0 \\ \frac{2}{3} & 0 & \frac{1}{3}\\ \frac{2}{3} & 0 & 0 \end{bmatrix}$$ which you can then ...

Two states communicate with each other if both are reachable from one another by a sequence of transitions that have positive probability. This is an equivalence relation which yields a set of communicating classes. A class is closed if the probability of leaving the class is zero. A Markov chain is irreducible if there is one communicating class, the state space. A state i has period if is the greatest common divisorof the number of transitions by which i can b…
