Exact cir process simulation
Webgrowth and the Cox-Ingersoll-Ross (CIR) model for interest rates. The former belongs to the D2-class, whereas the latter is a diffusion process that is outside the D2-class, and it is used to illustrate how our exact methods can be extended for processes for which the EA2 algorithm is not applicable.

Web1. The variance process in the Heston model (i.e., CIR process) is notorious for the simulation. A typical Euler/Milstein scheme ends up with negative variance in a high portion of paths. Making it positive by np.abs () is distorting the true distribution. Consider Andersen (2008)'s QE scheme to resolve this issue: WebDec 1, 2024 · We introduce a broad family of generalised self-exciting point processes with CIR-type intensities, and we develop associated algorithms for their exact simulation. …

The Heston model is then completed by prescribing the evolution of S by dSt = µSt dt+ p Vt St ρdW1 t + p 1 −ρ2 dWt 2, where W2 t is an independent scalar Wiener process. The additional parameter µ is positive, while ρ ∈(−1,1). The transition probability density of the CIR process is known explicitly ...
