Bayesian Inference: A statistical method that uses Bayes' theorem to update the probability for a hypothesis as more evidence or information becomes available.

Markov Chain: A stochastic process that undergoes transitions from one state to another within a finite or countable number of possible states, characterized by the Markov property where future states depend only on the current state.

Posterior Distribution: The distribution of an unknown quantity, updated after taking into account new evidence, reflecting the degree of belief in various values of the parameter after observing data.
