WebEdit. View history. From Wikipedia, the free encyclopedia. In statistics, the generalized Dirichlet distribution ( GD) is a generalization of the Dirichlet distribution with a more general covariance structure and almost twice the number of parameters. Random vectors with a GD distribution are completely neutral . [1] The density function of is.
