摘要:We study asymptotic expansion of the likelihood of a certain class ofGaussian processes characterized by their spectral density fθ. We consider the casewhere fθ(x) ∼x→0 |x|−α(θ)Lθ(x) with Lθ a slowly varying function and α(θ) ∈ (−∞, 1). We prove LAN property for these models which include in particularfractional Brownian motion or ARFIMA processes.
