Let {bH(t), t∈ℝ} be the fractional Brownian motion with parameter 00tσ(X(u)) dbH(u)+∫0tμ(X(u)) du.
¶
In different particular models where σ(x)=σ or σ(x)=σ x and μ(x)=μ or μ(x)=μ x, we propose a central limit theorem for estimators of H and of σ based on regression methods. Then we give tests of the hypothesis on σ for these models. We also consider functional estimation on σ(⋅) in the above more general models based in the asymptotic behavior of functionals of the 2nd-order increments of the fBm.
