“…Thus the FPT approach is beneficial for models based on stochastic processes such as random walks or diffusion, as it offers a way to calculate the closed-form solution of the pdf. In most applications it is easier to deal with the pdf than the stochastic process (Ma, Krings, & Millar, 2009). The resulting distribution, denoted (c, td) ∼ WFPT(v, a, z), is called a Wiener first-passage time (WFPT) distribution.…”
