## What is mean recurrence time?

Mean recurrence times. This means that once the chain is in some recurrent class R it stays there forever.

What is an ergodic Markov chain?

A Markov chain is said to be ergodic if there exists a positive integer such that for all pairs of states in the Markov chain, if it is started at time 0 in state then for all , the probability of being in state at time is greater than .

### What is first passage time Markov chain?

The mean first passage time in going from state i to statej in a Markov chain is the mean length of time required to go from state t to state./ for the first time. Mean first passage times are useful statistics for analysing the behaviour of various Markovian models of random processes.

What is mean recurrence time in Markov chain?

The mean recurrence times of (countable state) irreducible and positive recurrent Markov chains are the spanning tree invariants of the first return loop systems. Henceforth, for (countable state) irreducible and positive recurrent Markov chains, spanning tree invariants of loop systems are mean recurrence times.

#### What does recurrence mean?

: a new occurrence of something that happened or appeared before : a repeated occurrence Scientists are working to lower the disease’s rate of recurrence. Long-term drug therapy is associated with frequent recurrences and adverse effects, however.—

What is a mean recurrence time Markov chain?

## Why is Ergodicity important?

Ergodicity is important because of the following theorem (due to von Neumann, and then improved substantially by Birkhoff, in the 1930s). The ergodic theorem asserts that if f is integrable and T is ergodic with respect to P, then ⟨f⟩x exists, and P{x:⟨f⟩x=¯f}=1.

What is absorbing state?

An absorbing state is a state that, once entered, cannot be left. Like general Markov chains, there can be continuous-time absorbing Markov chains with an infinite state space.

### Where is the male first passage?

In most male voices, the first passage starts around an E♭4/E4, the second passage around an A♭4/A4, and the third passage around an E♭5/E5.

What is Gambler’s ruin problem?

The Gambler’s Ruin problem is essentially a Markov chain where the sequence of wealth amounts that gambler A has at any point in time determines the underlying structure. That is, at any point in time n, gambler A can have i wealth, where i also represents the state of the chain at time n.

#### How to calculate the mean first passage time?

Let us now define two matrices \\matM and \\matD. The ij th entry mij of \\matM is the mean first passage time to go from si to sj if i ≠ j; the diagonal entries are 0. The matrix \\matM is called the The matrix \\matD is the matrix with all entries 0 except the diagonal entries dii = ri.

How is mean recurrence time related to mean first passage time?

Mean Recurrence Time A quantity that is closely related to the mean first passage time is the defined as follows. Assume that we start in state si; consider the length of time before we return to si for the first time.

## Which is closely related to the mean first passage time?

A quantity that is closely related to the mean first passage time is the defined as follows. Assume that we start in state si; consider the length of time before we return to si for the first time.
