Let X be a positive recurrent regenerative process on state space S with steady-state distribution π. Given a function f: S-> R, we consider the problem of estimating the steady-state central moments μk(f)=∫S(f(x)-r)kπ(dx) where r is the steady-state mean of f(X(.)). We obtain strong laws, central limit theorems, and confidence intervals for our estimators, and present numerical results.
