Marco Inancio posted this one on the Stan users list: ( Statement 1) If the kinetic energy equation comes from a distribution $L$ which is not a symmetric distribution, then thanks to the “Conservation of the Hamiltonian” property we’ll still be able to accept the proposal with probability 1 if we are computing the Hamiltonian’s […] The post How Hamiltonian Monte Carlo works appeared first on Statistical Modeling, Causal Inference,…
