Summary

The Wishart variate is a k-dimensional generalization of the chi-squared variate, which is the sum of squared normal variates. It performs a corresponding role for multivariate normal problems as the chi-squared does for the univariate normal. This chapter shows the variate relationships of the Wishart (Central) Distribution.
