Reference problem

[Felipe-4]

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. )
