R: Computation of the First Passage Time From Trajectories

WebThe theory of first-passage times of Brownian motion is developed in general, and it is shown that for certain special boundaries—the only ones of any importance—mean first-passage times can be derived very simply, avoiding the usual method involving series. WebApr 1, 2024 · The mean first passage time (MFPT) is then defined as (6) E T r S = T ( r S) = ∫ 0 ∞ t f ( t r S) d t = − ∫ 0 ∞ t ∂ ∂ t S ( t r S) d t, = ∫ 0 ∞ S ( t r S) d t. This result is obtained after integrating by parts and noting that the searcher will eventually reach the target since the domain is confined.
