The topics include fractional Brownian motion and related processes, parametric estimation for fractional Ornstein-Uhlenbeck type processes, sequential inference and non-parametric inference for processes driven by fractional Brownian motion, parametric estimation for processes driven by a fractional Browning sheet, and self-similarity index estimation.
Characterizing the instantaneous investment opportunity set by the real interest rate and the maximum Sharpe ratio, Brennan, Wang, and Xia posit a simple model of time-varying investment opportunities in which these two variables follow correlated Ornstein-Uhlenbeck processes.
We assume the short interest rate, which is the only state variable, is given by the following stochastic differential equation: [Mathematical Expression Omitted], yielding the Ornstein-Uhlenbeck process, where m, q, and v are non-negative constants interpretable as the long-range mean to which [r.
