+estimate of the Bayesian evidence for a given likelihood and prior.
+@code{nestcheck} provides Python utilities for analysing samples produced by
+nested sampling, and estimating uncertainties on nested sampling
+calculations (which have different statistical properties to calculations
+using other numerical methods).")
