Steps of the gibbs algorithm

Gibbs sampling is named after the physicist Josiah Willard Gibbs, in reference to an analogy between the sampling algorithm and statistical physics. The algorithm was described by brothers Stuart and Donald Geman in 1984, some eight decades after the death of Gibbs, and became popularized in the statistics community for calculating marginal probability distribution, especially the posterior distribution. 網頁2 The Gibbs Sampler 4 3 The detailed balance condition 5 4 The Metropolis-Hastings algorithm 6 5 The reversible-jump algorithm 8 6 A changepoint example 10 6.1 A loosely adapted implementation of birth and death . . . . . . . . . . . . . . .11 6.2 A tightly adapted
