Abstract
For scalar diffusion models with unknown drift function asymptotic equivalence in the sense of Le Cams deficiency between statistical experiments is considered under longtime asymptotics A local asymptotic equivalence result is established with an accompanying sequence of simple Gaussian shift experiments Corresponding globally asymptotically equivalent experiments are obtained as compound experiments The results are extended in several directions including time discretisation An explicit transformation of decision functions from the Gaussian to the diffusion experiment is constructed
