Bayesianz Research Group: What's been happening
- 13 Aug 2014. Brendon Brewer on "Trans-dimensional Bayesian Inference and Nested Sampling"
(i.e., how to make your reversible jump even jumpier!).
- 27 Aug 2014. Russell Millar on foundations of inference "Shaky foundations: what they don't tell you as an under-grad".

- 10 Sept 2014. Alex Popinga on "Sticky stochastic inference in infectious diseases".
- 24 Sept 2014. Stephane Guindon gave a very insightful look at the motivation of nested sampling. A key step was to utilize the alternative formula for an expected value, expressed as the integral of (1-F(y)) (one minus the cdf).
- 8 Oct 2014. Patricio Russel presented his PhD provisional talk on "Better Proposals for Bayesian phylogenetic".
- 22 Oct 2014. Russell presented the exchange paradox as an example of inconsistent inference
arising from uniform priors. Then, Stephane presented reversible-jump calculations for trans-dimensional
proposal distributions, showing how this resulted in a simple Metropolis-Hasting acceptance probability.
- 5 Nov 2014. Tim Vaughan lead a discussion on Richard Cox's seminal 1946 paper on "Probability, Frequency and Reasonable,Expectation", showing how the rules of probability can be justified from axiomatic arguments for plausibility of events.
- 19 Nov 2014. Russell Millar spoke on new developments in model comparison using information criteria, "Beyond DIC: New developments in Bayesian model comparison".
We saw that the choice of targeted loss is a fundamental decision.
