Store evidence #156

Open vetlewi opened 4 years ago

vetlewi commented 4 years ago

I've added an attribute to the ResultsNormalized to store the global evidence from the MultiNest results. Could be useful down the line.

Good idea.

How does this act when one employs the "stagewise" normalization? normalizeStagewise in EnsembleNormalizer? I havn't thought "enough" about it, but I assume the evidence should be multiplied somehow by the distance of the chosen B (-> Gg) from the experimental Gg. So this process here should modify the evidence I guess:

Huh, haven't though about that. I guess it depends on the likelihood and prior to be separable (with regards to Gg)? I don't feel like I know enough Bayesian statistics to confidently give an answer :p

Unless this is very urgent, I'll think more about it after I've handed in my thesis in December. Writing on the main body of it now ;).

Not very urgent. Can always pull to a local branch for now.
