Webdynesty¶. dynesty is a Pure Python, MIT-licensed Dynamic Nested Sampling package for estimating Bayesian posteriors and evidences. See Crash Course and Getting Started … WebNested sampling (NS) computes parameter posterior distributions and makes Bayesian model comparison computationally feasible. Its strengths are the unsupervised navigation of complex, potentially multi-modal posteri-ors until a well-defined termination point. A systematic literature review of nested sampling algorithms and variants is presented.
