The\npackage contains functions aimed at evaluating the exact\ndistribution of quadratic forms (QFs) and ratios of QFs. In\nparticular, we propose to evaluate density, quantile and\ndistribution functions of positive definite QFs and ratio of\nindependent positive QFs by means of an algorithm based on the\nnumerical
