WebTo implement the Gibbs sampler we require the ability to draw from the posterior conditionals of the model. (Note that some of the previous methods on direct simulation could come in useful in this regard!) Although the joint posterior density f( jy) may often be intractable, the complete conditionals ff( jj j;y)gK j=1, (with Webthe system in the Grand Canonical Ensemble. The Gibbs density matrix ρG and the Grand partition Function ZG are ρG ≡ e−β(H− µN), Z G = Tr ρG = e −βΩG (3.20) where β= 1/(kT), His the Hamiltonian, Nis the particle number operator, which commutes with the Hamiltonian, [N,H] = 0, ZG is the grand partition function and ΩG 1
