%description
The computation of quadratic form (QF) distributions is often not trivial
and it requires numerical routines. The package contains functions aimed
at evaluating the exact distribution of quadratic forms (QFs) and ratios
of QFs. In particular, we propose to evaluate density, quantile and
distribution functions of positive definite QFs and ratio of independent
positive QFs by means of an algorithm based on the numerical inversion of
Mellin transforms.
