WebJul 17, 2024 · Method 1: We can determine if the transition matrix T is regular. If T is regular, we know there is an equilibrium and we can use technology to find a high power of T. For the question of what is a sufficiently high power of T, there is no “exact” answer. Select a “high power”, such as n = 30, or n = 50, or n = 98. WebAn aperiodic Markov chain with positive recurrent states While a recurrent state has the property that the Markov chain is expected to return to the state an infinite number of times, the Markov chain is not necessarily … WebApr 10, 2015 · A Markov Chain is aperiodic if all states have period 1. In your example, it's possible to start at 0 and return to 0 in 2 or 3 steps, therefore 0 has period 1. Similarly, 1 and 2 also have period 1. So the Markov chain is aperiodic.
