Sampler Statistics

When checking for convergence or when debugging a badly behaving sampler, it is often helpful to take a closer look at what the sampler is doing. For this purpose some samplers export statistics for each generated sample.

For discussion on the theory behind divergences and how they relate to biased inference, you can read A Conceptual Introduction to Hamiltonian Monte Carlo.
