class MultivariateGaussian extends Serializable

:: DeveloperApi :: This class provides basic functionality for a Multivariate Gaussian (Normal) Distribution. In the event that the covariance matrix is singular, the density will be computed in a reduced dimensional subspace under which the distribution is supported. (see http://en.wikipedia.org/wiki/Multivariate_normal_distribution#Degenerate_case)
