Approximations to Joint Distributions of Definite Quadratic Forms
Abstract
Multidimensional Wilson-Hilferty transformations support Gaussian approximations to certain joint distributions of quadratic forms in Gaussian variables. Central and noncentral distributions are studied and applications are noted. Parameters of the approximating distributions are given up to terms of order omicron(v to the minus 3rd power) in the degrees of freedom (nu). Numerical studies validate using these approximations over a range of parameters for an essential subclass of the distributions.
