WebThe Metropolis algorithm is a special case of the Metropolis-Hastings in which the proposal model is symmetric. That is, the chance of proposing a move to μ ′ μ′ from μμ is equal to that of proposing a move to μμ from μ ′ μ′: q(μ ′ μ) = q(μ μ ′)q(μ′ μ) = q(μ μ′). Thus, the acceptance probability (7.3) simplifies to WebJackknife, bootstrap methods, the EM algorithms, and Markov chain Monte Carlo (MCMC) methods such as the Metropolis algorithm, Metropolis-Hastings algorithm and the Gibbs sampler.
