....rates also can arise in the estimation of steady state means as in Example 4.3 when there is long range dependence in the underlying stochastic process X. Instead of (16) a FCLT may hold with g 1 2. For examples of long range dependence, see Mandelbrot (1977) Taqqu (1982) Cox (1984) Vervaat (1985) and references cited there. 6. Supercanonical Estimator Convergence Rates In this section we give an example of an estimator having a supercanonical convergence rate. This estimator may have some intrinsic interest, but we present it primarily to illustrate how supercanonical convergence rates ....

....2 . Sample path properties of Brownian motion have been well studied. As Brownian motion, fractional Brownian motion is also sample continuous, nowhere di erentiable and of unbounded variation almost surely. For sample path properties of general selfsimilar process with stationary increments, see [Ver85], and for that of selfsimilar stable processes with stationary increments, see [KonMae91] 6 Several properties of trajectories of multidimensional fractional Brownian motion with multiparameter have also been studied. Let fBH (t) t 2 R N g be a mean zero Gaussian process with covariance ....
