Branch: CURRENT, Version: 2.18.1, Package name: stan-math-2.18.1, Maintainer: minskim

The Stan Math Library is a C++, reverse-mode automatic differentiation
library designed to be usable, extensive and extensible, efficient,
scalable, stable, portable, and redistributable in order to facilitate
the construction and utilization of algorithms that utilize
derivatives.
