Estimating Evidence using MultiNest sampler #381

Closed SuvedhaNaik closed 1 month ago

SuvedhaNaik commented 5 months ago

Hello,

I want to use 21CMMC to compare different models against some data sets. I want to perform a Bayesian model comparison to do so. Since 21CMMC already has the MultiNest sampler, is there a way to get the Bayesian evidence of the model?

Thanks in advance.

The evidence should be in the MultiNest output, i.e. datadir/Multinest/model_namestats.dat
