Abstract

The first passage time problem through a monotone boundary is considered for stationary Gaussian processes possessing rational spectral densities. Using a parallel procedure to simulate sample paths, estimates of the upcrossing probability density function of the first passage time are constructed. A comparison is provided with the numerical results obtained by Kostyukov via numerical solution of a Volterra integral equation. Finally, the effect of covariance's oscillatory components and of the behaviour of the boundary on the shape of the upcrossing FPT densities are pinpointed
