Abstract

If ΞΎ(t) is the solution of homogeneous SDE in R
m, and T
βˆƒ is the first exit moment of the process from a small domain D
βˆƒ, then the total expansion for the following functional showing independence of the exit time and exit place is
$$Eexp( - \lambda T_\varepsilon )f(\frac{{\xi (T_\varepsilon )}}{\varepsilon }) - Eexp( - \lambda T_\varepsilon )Ef(\frac{{\xi (T_\varepsilon )}}{\varepsilon }),\varepsilon \searrow 0,\lambda > 0.$$

In this note we investigate asymptotic properties of an estimator, called the Euler estimator, which is obtained by maximizing the likelihood function of the process discretized by the Euler method. By linking the Euler estimator of the coefficients of the drift function of a stochastic differential
