PAUL FEARNHEAD THESIS

An introduction to hidden Markov models. Fearnhead, ; and for HMM dependence in the state value for neighbouring segments Fearnhead and Vasileiou, For an efficient independence proposal we require a good approximation to p xt: To avoid this Shephard and Pitt suggest randomly choosing the blocks to be updated for each application of the independence proposal. Ombination in the human genome will provide insight into the evolution PDF document – DocSlides- To my examiners, Paul Fearnhead and Jonathan Marchini, thank you for taking the time to consider this thesis.

The Annals of Applied Statistics 9 Even looking at the worse-case acceptance rates across all runs, we have acceptances rates greater then 0. Kallol Roy for their help on Particle Filters.

In Computing Science and Statistics: Secondly we will consider moves to update the parameters. This is most easily and commonly implemented for models where we can simulate di- rectly from p x1: Detecting homogeneous segments in DNA sequences by using hidden Markov models.

Discrete Hidden Markov Model A general class of models occurs when the underlying state is a discrete-valued Markov model, with a finite state-space. American Journal of Human Genetics77 However, overall we see that the block updates are particularly efficient for the SV model. As above, we palu mixing by looking at the lag-1 autocorrelation of the mean square error in the estimate of the state process.

Two features are striking. For fuller details see Hull and White and Shephard Hidden Markov models for speech recognition. The advantage of this is that the costly forward-recursion is only required once, as opposed to at every iteration of the MCMC algorithm.
