%description
Performs simulation and inference of diffusion processes on circle.
Stochastic correlation models based on circular diffusion models are
provided. For details see Majumdar, S. and Laha, A.K. (2024) "Diffusion on
the circle and a stochastic correlation model"
<doi:10.48550/arXiv.2412.06343>.
