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. – This is for the use of researchers in these numerical approximation implementations, notably for my own use in order to improve R‘s own pbeta(), qgamma(), ..., etc: {’"dpq"'-functions}. – We plan to complement with 'DPQmpfr' to be suggested later.
