InverseWishart Class

Multivariate Inverse Wishart distribution. This distribution is parameterized by the degrees of freedom nu and the scale matrix S. The inverse Wishart distribution is the conjugate prior for the covariance matrix of a multivariate normal distribution. Wikipedia - Inverse-Wishart distribution.
