Title: RWiener package Author: Dominik Wabersich Affiliation: Ludwig Maximilians University Munich Abstract: The RWiener package provides functions to implement the Wiener diffusion process model in R. The functions include the density function, the cumulative distribution function, a quantile function, and a function to do random sampling. The computations are performed with highly efficient algorithms taken from recent scientific papers. RWiener also provides additional functions for further inference or to do parameter estimation.
