Geyer (1992) shows that discarding $k-1$ out of every $k$ observations will not improve statistical efficiency, as quantified through variance in a given computational budget. That observation is often taken to mean that thinning MCMC output cannot improve statistical efficiency. Here we suppose that it costs one unit of time to advance a Markov chain and then $\\theta>0$ units of time to compute a sampled quantity of interest. For a thinned process, that cost $\\theta$ is incurred less often, so it can be advanced throu","authors_text":"Art B.
