Analytic crossing probabilities for certain barriers by Brownian motion

چکیده

We calculate crossing probabilities and one-sided last exit time densities for a class of moving barriers on an interval [0, T ] via Schwartz distributions. We derive crossing probabilities and first hitting time densities for another class of barriers on [0, T ] by proving a Schwartz distribution version of the method of images. Analytic expressions for crossing probabilities and related densities are given for new explicit and semi-explicit barriers.

Linear and Nonlinear Boundary Crossing Probabilities for Brownian Motion and Related Processes

Wepropose a newmethod to obtain the boundary crossing probabilities or the first passage time distribution for linear and nonlinear boundaries for Brownian motion. The method also covers certain classes of stochastic processes associated with Brownian motion. The basic idea of the method is based on being able to construct a finite Markov chain, and the boundary crossing probability of Brownian...

Crossing Probabilities for Diffusion Processes with Piecewise Continuous Boundaries

We propose an approach to compute the boundary crossing probabilities for a class of diffusion processes which can be expressed as piecewise monotone (not necessarily one-to-one) functionals of a standard Brownian motion. This class includes many interesting processes in real applications, e.g., Ornstein-Uhlenbeck, growth processes and geometric Brownian motion with time dependent drift. This m...

Boundary Crossing Probabilities for Stationary Gaussian Processes and Brownian Motion1

Let X(t) be a stationary Gaussian process, /(/) a continuous function, and T a finite or infinite interval. This paper develops asymptotic estimates for P(X(t) > fit), some /er) when this probability is small. After transformation to an Ornstein Uhlenbeck process the results are also applicable to Brownian motion. In that special case, if W(t) is Brownian motion, / is continuously differentiabl...

Approximations for weighted Kolmogorov-Smirnov distributions via boundary crossing probabilities

A statistical application to Gene Set Enrichment Analysis implies calculating the distribution of themaximum of a certain Gaussian process, which is a modification of the standard Brownian bridge. Using the transformation into a boundary crossing problem for the Brownian motion and a piecewise linear boundary, it is proved that the desired distribution can be approximated by an n-dimensional Ga...

On Approximation Rates for Boundary Crossing Probabilities for the Multivariate Brownian Motion Process

Motivated by an approximation problem from mathematical finance, we analyse the stability of the boundary crossing probability for the multivariate Brownian motion process, with respect to small changes of the boundary. Under broad assumptions on the nature of the boundary, including the Lipschitz condition (in a Hausdorff-type metric) on its time cross-sections, we obtain an analogue of the Bo...
