The holonomic gradient descent (HGD, hgd) gives a method to find maximal likelihood estimates by utilizing the HGM. } \details{ \tabular{ll}{ Package: \tab hgm\cr Type: \tab Package\cr License: \tab GPL-2\cr LazyLoad: \tab yes\cr } The HGM and HGD are proposed in the paper below. This method based on the fact that a broad class of normalization constants of unnormalized probability distributions belongs to the class of holonomic functions, which are solutions of holonomic systems of linear partial differential equations. } \note{ This package includes a small subset of the Gnu scientific library codes (\url{http://www.gnu.org/software/gsl/}).
