DPQmpfr (version 0.3-3)

DPQ (Density, Probability, Quantile) Distribution Computations using MPFR

Description

An extension to the 'DPQ' package with computations for 'DPQ' (Density (pdf), Probability (cdf) and Quantile) functions, where the functions here partly use the 'Rmpfr' package and hence the underlying 'MPFR' and 'GMP' C libraries.
