Talk:Reversible-jump Markov chain Monte Carlo

It isn't clear what the term $$q_{mm'}(m,u)$$ is intended to represent in the acceptance equation. Is it a separate proposal distribution? This factor seems to correspond somehow with the determinant of the Jacobian at the end. Neither factor's meaning is intuitively obvious nor clear from the article.
