for the corresponding likelihood ratio test statistics themselves. The GIG distribution is also the basis for a number of wrapped distributions in the wrapped gamma family. As being a special case of the generalized chi-squared distribution, there are many other applications; for example, in renewal theory and in multi-antenna wireless communications. Computer modules Modules for the computation of the p.d.f. and c.d.f. of both the GIG and the GNIG distributions are made available at this web-page on near-exact distributions.
