Orthogonal gamma-based expansion for the CIR's first passage time distribution

E Di Nardo, G D'Onofrio, T Martini - arXiv preprint arXiv:2402.00833, 2024 - arxiv.org
In this paper we analyze a method for approximating the first-passage time density and the
corresponding distribution function for a CIR process. This approximation is obtained by …
