In 2011, we introduced the Holonomic Gradient Method (HGM) as a new approach to multivariate distribution theory. It is a general method applicable when the density functionis “holonomic” in the random variablesxas well as the parameters. Since the multivariate normal density is holonomic, HGM is applicable to the whole classical distribution theory based on the multivariate normal distribution. In fact since 2011, we applied HGM to many problems of classical multivariate distribution theory and showed that some difficult distributional problems, such as those involving hypergeometric functions of a matrix argument, can be successfully treated by HGM. In this article, we discuss the origin, the basic theory and some applications of HGM to multivariate distribution theory.
