Hi all,

I’m new to Stan and I’d like your insight on how Stan works. So my question is: Let’s assume I have a Bayesian Hierarchical Model with **x** number of parameters. Does Stan use the Hamiltonian system of equations to update all parameters at once? Or, say, it updates them one-at-a-time? Maybe in blocks of parameters?

I would appreciate your knowledge on this one.

Thanks,

Georgios
