Abstract EN
Consider an Ornstein-Uhlenbeck process driven by a fractional Brownian motion.
It is an interesting problem to find criteria for whether the process is stable or has a unit root, given a finite sample of observations.
Recently, various asymptotic distributions for estimators of the drift parameter have been developed.
We illustrate through computer simulations and through a Stein's bound that these asymptotic distributions are inadequate approximations of the finite-sample distribution for moderate values of the drift and the sample size.
We propose a new model to obtain asymptotic distributions near zero and compute the limiting distribution.
We show applications to regression analysis and obtain hypothesis tests and their asymptotic power.
