Some simple test problems for nested sampling codes (or other Bayesian sampling methods). These include multidimensional normal distributions, generalized Rosenbrock distributions, and multidimensional log-gamma distributions.
Python scripts to perform each test using MultiNest can be found in the multiNest
directory.
The emcee
directory includes and example MultiNest output, a script to initialize an emcee analysis based of of nested sampling outputs, and a script to run the log-gamma problem using emcee.
The ultraNest
directory includes and example MultiNest output and a script to run the log-gamma problem, utilizing the warm starting feature of the UltraNest sampler.
Results for these test problems are collected in https://arxiv.org/abs/2404.16928.
