TheMCMC defines transition probabilities that ensure convergence to the stationary distribution. So, what is “Stationary Distribution”?

Stationary Distribution

If a distribution satisfy below, it is said as “Stationary Distribution”.

\int p_{*}(x) p(x, y) \, dx = p_{*}(y)

A sufficient condition for ( p ) to become a stationary distribution is the detailed balance condition.

Detailed Balance Condition

The condition required for a Markov chain to converge to a stationary distribution is called the detailed balance condition.

Ergodicity

Additionally, the property that allows convergence to the stationary distribution from any initial distribution is known as ergodicity.
