Manoukian and Nadeau (1988) show that the mean of a hyperbolic secant sample is closely normal even for very small n. In a similar way, standard nonlinear least squares methods can be used to estimate βgiven a more general correlation function ζ i = g(w i,β) where g(·) is some known function.

We first build 3-dimensional normally hyperbolic invariant cylinders of limited regularity, but of large size, extrapolating on [Be3] and [KZZ]. Once these cylinders are constructed we use versions of Mather variational method developed in Bernard [Be1], Cheng-Yan [CY1, CY2].
