The sampling-importance resampling (SIR) algorithm aims at drawing a random sample from a target distribution π. First, a sample is drawn from a proposal distribution "q", and then from this a smaller sample is drawn with sample probabilities proportional to the importance ratios π/"q". We...

Necessary and sufficient conditions for uniform geometric convergence in the relative supremum norm of the Metropolis-Hastings simulation algorithm with a general generating function are established. An explicit expression for the convergence rate is given.
