Query: Statistical analysis of the mixed fractional Ornstein--Uhlenbeck process   This paper addresses the problem of estimating drift parameter of the
Ornstein - Uhlenbeck type process, driven by the sum of independent standard
and fractional Brownian motions. The maximum likelihood estimator is shown to
be consistent and asymptotically normal in the large-sample limit, using some
recent results on the canonical representation and spectral structure of mixed
processes.
