Abstract.
This paper defines an approximation scheme for a solution of t
he Poisson equation of
a geometrically ergodic Metropolis-Hastings chain Φ. The s
cheme is based on the idea of weak
approximation and gives rise to a natural sequence of contro
l variates for the ergodic average
S
k
(
F
) = (1
/k
)
∑
k
i
=1
F
(Φ
i
), where
F
is the force function in the Poisson equation. The main
results show that the sequence of the asymptotic variances (
in the CLTs for the control-variate
estimators) converges to zero and give a rate of this converg
ence. Numerical examples in the case
of a double-well potential are discussed.
