%description
Evaluates moments of ratios (and products) of quadratic forms in normal
variables, specifically using recursive algorithms developed by Bao and
Kan (2013) <doi:10.1016/j.jmva.2013.03.002> and Hillier et al. (2014)
<doi:10.1017/S0266466613000364>. Also provides distribution, quantile, and
probability density functions of simple ratios of quadratic forms in
normal variables with several algorithms. Originally developed as a
supplement to Watanabe (2023) <doi:10.1007/s00285-023-01930-8> for
evaluating average evolvability measures in evolutionary quantitative
genetics, but can be used for a broader class of statistics. Generating
functions for these moments are also closely related to the top-order
zonal and invariant polynomials of matrix arguments.
