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. The common ancestor at a non-neutral locus.

We give details of the methods used for the latter two below. Some MCMC runs had acceptance rates that are too small to appear on the plot. Within such an experiment we are able to choose the next stimulus level based on the past observations. Journal of Molecular Evolution 74

Examples of adaptive MCMC. Fwarnhead Xn is simulated from the filtering density Pr Xn y1: Random weight particle filtering of continuous-time processes. Ideally we would update the whole state process in one move, and in some cases it turns out that this is possible to do from the full-conditional, so that moves are always accepted.


That is we have a disjoint set of parameters for each of the K likelihood models.

These experiments involve a series of stimuli being applied to a motor unit, with whether or not the motor unit fires for each stimulus being recorded. As above, we evaluate mixing by looking at the lag-1 autocorrelation of the mean square error in the estimate of the state process. We will apply this loss function to the estimates of target quantiles from the stimulus-response curve. As seen above, whether this is the case will depend pahl the amount of dependence in the state-model.
