Functions

apply_boundaries_(u_prop, periodic, reflective)

Apply the periodic and reflective boundaries and test if we are inside the unit cube.

propose_differential_evolution(u, live, n, ...)

Propose a new point using ensemble differential evolution (ter Braak + (2006)).

propose_volumetric(u, axes, scale, n, ...)

Propose a new point using the default dynesty proposal.

Classes

ACTTrackingEnsembleWalk(**kwargs)

Run the MCMC sampler for many iterations in order to reliably estimate the autocorrelation time.

AcceptanceTrackingRWalk(**kwargs)

This is a modified version of dynesty.sampling.sample_rwalk that runs the MCMC random walk for a user-specified number of a crude approximation to the autocorrelation time.

BaseEnsembleSampler(**kwargs)

EnsembleAxisSamplerArgument(u, loglstar, ...)

EnsembleSamplerArgument(u, loglstar, ...)

EnsembleWalkSampler(**kwargs)
