[ascl:1502.011] PolyChord: Nested sampling for cosmology
Handley, W. J.; Hobson, M. P.; Lasenby, A. N.

PolyChord is a Bayesian inference tool for the simultaneous calculation of evidences and sampling of posterior distributions. It is a variation on John Skilling's Nested Sampling, utilizing Slice Sampling to generate new live points. It performs well on moderately high dimensional (~100s D) posterior distributions, and can cope with arbitrary degeneracies and multimodality.
