Estimating Evidence with MultiNest sampler #82

Open SuvedhaNaik opened 2 months ago

SuvedhaNaik commented 2 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.

Yes -- use the multinest sampler and read the output files to get the evidence, just as you normally would for MultiNest. I hope that helps!
