Abstract
I call
an MCMC algorithm "honest" if it is possible to calculate standard errors
using a valid central limit theorem along with a consistent estimate of
the (unknown) asymptotic variance. In this talk, I will explain how drift
and minorization conditions on the underlying Markov chain make honest MCMC
possible. (This is joint work with Galin Jones, Brett Presnell and Jeffrey
Rosenthal.)
