%description
Provides the probability density function (PDF), cumulative distribution
function (CDF), the first-order and second-order partial derivatives of
the PDF, and a fitting function for the diffusion decision model (DDM;
e.g., Ratcliff & McKoon, 2008, <doi:10.1162/neco.2008.12-06-420>) with
across-trial variability in the drift rate. Because the PDF, its partial
derivatives, and the CDF of the DDM both contain an infinite sum, they
need to be approximated. 'fddm' implements all published approximations
(Navarro & Fuss, 2009, <doi:10.1016/j.jmp.2009.02.003>; Gondan, Blurton, &
Kesselmeier, 2014, <doi:10.1016/j.jmp.2014.05.002>; Blurton, Kesselmeier,
& Gondan, 2017, <doi:10.1016/j.jmp.2016.11.003>; Hartmann & Klauer, 2021,
<doi:10.1016/j.jmp.2021.102550>) plus new approximations. All
approximations are implemented purely in 'C++' providing faster speed than
existing packages.
