Abstract: | We consider the problem of the density and drift estimation by the observation of a trajectory of an
\mathbbRd{\mathbb{R}^{d}}-dimensional homogeneous diffusion process with a unique invariant density. We construct estimators of the kernel type based
on discretely sampled observations and study their asymptotic distribution. An estimate of the rate of normal approximation
is given. |
