UltraNest -- a robust, general purpose Bayesian inference engine

Understand

UltraNest is a general-purpose Bayesian inference package for parameter estimation and model comparison.

• It allows fitting arbitrary models specified as likelihood functions written in Python, C, C++, Fortran, Julia or R.
• With a focus on correctness and speed (in that order), UltraNest is especially useful for multi-modal or non-Gaussian parameter spaces, computational expensive models, in robust pipelines.
• Parallelisation to computing clusters and resuming incomplete runs is available.
