Even faster and even more accurate first-passage time densities and distributions for the Wiener diffusion model

Gondan, Matthias ; Blurton, Steven P. ; Kesselmeier, Miriam


The Wiener diffusion model with two absorbing barriers is often used to describe response times and error probabilities in two-choice decisions. Different representations exist for the density and cumulative distribution of first-passage times, all including infinite series, but with different convergence for small and large times. We present a method that controls the approximation error of the ...
