Efficient Bayesian analysis of multiple changepoint models
Abstract:
We describe an efficient algorithm for Bayesian analysis of multiple
changepoint models. In many scenarios it enables iid samples from the
posterior distribution. Approximate versions (which introduce negligble
error) have a computational cost that is linear in the number of
observations -- and thus can be applied to large data sets (such as
arise in modern bioinformatic applications).
The method is demonstrated on applications that range from inference
about the divergence of Salmonella Typhi and Paratyphi A, to inference
about the Isochore structure of the human genome.
