Given a training sample of size m from a d-dimensional population, we
wish to allocate a new observation Z ∈ IRd to this population or to the noise.
We suppose that the difference between the distri...

We show how a description of Brownian exponential functionals as a renewal series gives access to the law of the hitting time of a square-root boundary by a Bessel process. This extends classical resu...
