Jump to Ergodicity - A state i is said to be ergodic if it is aperiodic and positive recurrent. In other words, a state i is ergodic if it is recurrent, has a period of 1, and has finite mean recurrence time. If all states in an irreducible Markov chain are ergodic, then the chain is said to be ergodic.‎Markov chain geostatistics · ‎Quantum Markov chain · ‎Markov chain Monte Carlo.

ERGODIC MARKOV CHAIN EBOOK


I guess that it suffices to show that it is Harris recurrent.

To ergodic markov chain Harris recurrence I guess that it ergodic markov chain to show there exists an atom obtained via splitting the chain after using minorization criteria the return time or hitting time to which has finite mean. Irreducibility of the transition graph of the state space means that a sample path cannot get trapped in smaller subsets of the state space, since one can go from everywhere to everywhere.

This implies, but one has to work this out, that the whole chain is ergodic: It eats exactly once a day.

ERGODIC MARKOV CHAIN EBOOK

If it ate cheese today, tomorrow it will eat lettuce or grapes with equal probability. It will not eat lettuce again tomorrow.

This creature's eating habits can be modeled with a Markov chain since its choice tomorrow depends solely on what it ate today, not what it ate yesterday or any other time in the past.

One statistical property that could be calculated is the expected percentage, over a long period, of the days on which the creature will eat grapes.

A series of independent events for example, a series of coin flips satisfies the formal definition of a Markov chain.

However, the theory is usually applied only when the probability distribution ergodic markov chain the next step depends non-trivially on ergodic markov chain current state.

Markov chain - Wikipedia

History[ edit ] Andrey Markov studied Markov chains in the early 20th century. Other early uses of Markov chains ergodic markov chain a diffusion model, introduced by Paul and Tatyana Ehrenfest inand a branching process, ergodic markov chain by Francis Galton and Henry William Watson inpreceding the work of Markov.

Informally, the first ensures that there is a sequence of transitions of non-zero probability from any state to any other, while the latter ensures that the states are not partitioned into sets such that all state transitions occur cyclically from one set to another.
