WebThe Metropolis–Hastings algorithm associated with a target density π requires the choice of a conditional density q also called proposal or candidate kernel. The transition from the value of the Markov chain ( X ( t)) at time t and its value at time t + 1 proceeds via the following transition step: Algorithm 1.
