Clustering using skewed multivariate heavy tailed distributions with flexible tail behaviour
Darren Wraith, Florence Forbes
The family of location and scale mixtures of Gaussians has the ability to generate a number of flexible distributional forms. It nests as particular cases several important asymmet…
Using informative priors in the estimation of mixtures over time with application to aerosol particle size distributions
Darren Wraith, Kerrie Mengersen, Clair Alston +2
The issue of using informative priors for estimation of mixtures at multiple time points is examined. Several different informative priors and an independent prior are compared usi…
CosmoPMC: Cosmology Population Monte Carlo
Martin Kilbinger, Karim Benabed, Olivier Cappe +7
We present the public release of the Bayesian sampling algorithm for cosmology, CosmoPMC (Cosmology Population Monte Carlo). CosmoPMC explores the parameter space of various cosmol…
Bayesian model comparison in cosmology with Population Monte Carlo
Martin Kilbinger, Darren Wraith, Christian P. Robert +6
We use Bayesian model selection techniques to test extensions of the standard flat LambdaCDM paradigm. Dark-energy and curvature scenarios, and primordial perturbation models are c…
Computational methods for Bayesian model choice
Christian P. Robert, Darren Wraith
In this note, we shortly survey some recent approaches on the approximation of the Bayes factor used in Bayesian hypothesis testing and in Bayesian model choice. In particular, we…
Dark energy constraints and correlations with systematics from CFHTLS weak lensing, SNLS supernovae Ia and WMAP5
M. Kilbinger, K. Benabed, J. Guy +15
We combine measurements of weak gravitational lensing from the CFHTLS-Wide survey, supernovae Ia from CFHT SNLS and CMB anisotropies from WMAP5 to obtain joint constraints on cosmo…
