Xi'an's Og

As I have a huge arXiv backlog and an even higher non-arXiv backlog, I cannot be certain I will find time to comment on those three recent and quite exciting postings connecting ABC with astro- and cosmo-statistics [thanks to Ewan for pointing out those to me!]:

• Weighted ABC: a new strategy for cluster strong lensing cosmology with simulations, by Madhura Killedar et al. [Madhura won one of the three prizes at the BAYESM meeting last year]:
  

  “We investigate the uncertainty in the calculated likelihood,and consequential ability to compare competing cosmologies…”

• Inflation, evidence and falsifiability, by Giulia Gubitosi et al.:
  

  “By considering toy models we illustrate how unfalsifiable models and paradigms are always favoured by the Bayes factor…”

• Bayesian model selection without evidences: application to the dark energy equation-of-state, by Sonke Hee et al.:
  

  “A method is presented for Bayesian model selection without explicitly computing evidences … without the need for reversible jump MCMC techniques.”
