Description

This is not so much a problem with the package per say, but a lack of references, and I don't know where else to post it. I looked to the paper and the github and there is no description of how the package calculates the figures, I saw just one comment in the paper: "it uses scatterplot matrix", which didn't clarify to me how the algorithm works.

(I am new to statistics overall, maybe it is obvious, I am just trying to understand why a grid calculation I did is giving different results than the mcmc for the marginalized posterior. )

Research direction

Start by reviewing the cited paper and the package's GitHub materials to identify how the figures and marginalized posterior are calculated. Done means adding references and a clear explanation of the algorithm, including enough detail to explain why grid calculations may differ from MCMC results.
