%description
Computations for approximations and alternatives for the 'DPQ' (Density
(pdf), Probability (cdf) and Quantile) functions for probability
distributions in R. Primary focus is on (central and non-central) beta,
gamma and related distributions such as the chi-squared, F, and t. -- For
several distribution functions, provide functions implementing formulas
from Johnson, Kotz, and Kemp (1992) <doi:10.1002/bimj.4710360207> and
Johnson, Kotz, and Balakrishnan (1995) for discrete or continuous
distributions respectively. This is for the use of researchers in these
numerical approximation implementations, notably for my own use in order
to improve standard R pbeta(), qgamma(), ..., etc: {'"dpq"'-functions}.
