BXA enables nested sampling in the X-ray spectral analysis environments Xspec/Sherpa for Bayesian Parameter Estimation and Model comparison.
copied from cf-staging / bxaBayesian X-ray Analysis (BXA) allows reliable parameter inference and model comparison in X-ray astronomy.
BXA connects the nested sampling algorithms MultiNest and UltraNest to the X-ray spectral analysis environments Xspec (https://heasarc.gsfc.nasa.gov/xanadu/xspec/) and Sherpa (http://cxc.cfa.harvard.edu/sherpa/).
This allows reliable and automatic Bayesian parameter estimation and model comparison.
