Markov chain - Wikipedia
https://en.wikipedia.org/wiki/Markov_chain
A Markov chain or Markov process is a stochastic model describing a sequence of possible events in which the probability of each event depends only on the state attained in the previous event. A countably infinite sequence, in which the chain moves state at discrete time steps, gives a discrete-time Markov chain (DTMC). A continuous-time process is called a continuous-time Markov chain(CTMC). It i…

18.12.2021 · The distribution is quite close to the stationary distribution that we calculated by solving the Markov chain earlier. In fact, rounded to two decimals it is identical: [0.49, 0.42, 0.09]. As we can see below, reconstructing the state transition matrix from the transition history gives us the expected result:

Aug 30, 2018 · An absorbing Markov chain is a Markov chain in which it is impossible to leave some states once entered. However, this is only one of the prerequisites for a Markov chain to be an absorbing Markov chain. In order for it to be an absorbing Markov chain, all other transient states must be able to reach the absorbing state with a probability of 1.

probability that the Markov chain is in a transient state after a large number of transitions tends to zero. – In some cases, the limit does not exist! Consider the following Markov chain: if the chain starts out in state 0, it will be back in 0 at times 2,4,6,… and in state 1 at times 1,3,5,…. Thus p(n) 00=1 if n is even and p(n)

Feb 03, 2018 · The fundamental matrix is N = ( I − Q) − 1 =. This matrix's entry ( i, j) is the expected value of visits at i before being absorbed if the chain starts at j (or the other way around, I don't remember, but luckily it doesn't matter in this case the matrix is symmetric). So the answer is. 1 2 ( 3 + 1) = 2.

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 \( n = 8 \).

02.02.2018 · Calculate the expected value for the amount of years till state $0$ is reached, if we started from state $2$. I took this question from an exam and try to solve it but I'm not sure how to do this correct? I'm a bit confused we need to work with expected value to calculate the required steps / years to get from state $2$ to state $0$.
