Sampling the posterior PDF over catalogs given a simulated image of a sparse stellar field. This inference problem had a phase transition so Nested Sampling was required.

Just a little animation I made to accompany this paper (http://www.mdpi.com/1099-4300/19/8/422) where I adapt Nested Sampling so that you can compute the Shannon entropy of a distribution without having to evaluate its density function (if you can sample it in an MCMC-like fashion, you can get its entropy).
The blue density is the one of interest. A red reference point is generated, and then green NS live points are evolved towards the reference point (leaving a trail of black triangles - NS dead points).

How do Bayesians predict the future?
And how do they calculate posteriors when computers are unavailable?

In this lecture I talk about three Bayesian models (sets of prior assumptions) that can be used in place of a classical two-sample t-test. This includes discussion of how to implement a spike-and-slab prior in JAGS, and hierarchical models.
