bilby.core.sampler.dynesty.dynesty_stats_plot(sampler)[source]

Plot diagnostic statistics from a dynesty run

The plotted quantities per iteration are:

nc: the number of likelihood calls
scale: the number of accepted MCMC steps if using bound="live" or bound="live-multi", otherwise, the scale applied to the MCMC steps
lifetime: the number of iterations a point stays in the live set

There is also a histogram of the lifetime compared with the theoretical distribution. To avoid edge effects, we discard the first 6 * nlive

Parameters:

sampler: dynesty.sampler.Sampler: The sampler object containing the run history.

Returns:
