Index … WebThe discrete bouncy particle sampler operates on the extended state space X × S, where S ⊆ X, and explores the extended target distribution ˜π(dx, du) = π(dx) ⊗ ρ(du), where ρ(du) is an auxiliary spherically symmetric distribution with support S ⊂ X. Section 2.2 describes several standard choices of auxiliary distributions.
