The common ancestor at a non-neutral locus. We will describe such an approach for the SV model of Example 1; and then discuss alternative approaches for block updates for models where it is not possible to draw from the full conditional distribution of the state. We give details of the methods used for the latter two below. Red lines show mean acceptance rates for each block size. Here we will look at the effect that block size has on acceptance probabilities for the SV model. Statistical Science 33

Updating state from its full conditional The forward-backward algorithm is a method for sampling from the full conditional of the state-process for discrete HMMs. Journal of Applied Probability , Paga con Paypal o Carta Paga ora. Plots of average acceptance rates for different block sizes and different data sets are shown in Figure 1. Biometrika , 97 , Dates First available in Project Euclid: In most applications it is straight-forward to implement an MCMC algorithm with 1.

This latter idea, and ideas related to it, has been used extensively within contin- uous time stochastic volatility models see e. However the former method can only be applied to a limited class of models, and the latter used the linear-Gaussian nature of the state-model.
