It is shown that the suitably normalized maximum likelihood estimators of some parameters of multidimensional Ornstein Uhlenbeck processes with coefficient matrix of a special structure have exactly a normal distribution. This result provides a generalization to an arbitrary dimension of the well-kn

โฆ Synopsis
Let x(t) be an Ornstein-Uhlenbeck process and y(t) a diffusion process. Formulae are obtained for the characteristic and probability density functions of x(T(y)), where T(y) is the first passage time of y(t) to the boundary y(t) --d, starting from y.

## Abstract This paper deals with optimal designs for Gaussian random fields with constant trend and exponential correlation structure, widely known as the OrnsteinโUhlenbeck process. Assuming the maximum likelihood approach, we study the optimal design problem for the estimation of the trend ยต and
Let Xt be a standard d-dimensional Brownian motion with drift c started at a รฟxed X0, and let T be the hitting time for a sphere or concentric spherical shell. By using an appropriate martingale, a Laplace-Gegenbauer transform of the joint distribution of T and XT is determined.
