Convolution of Gamma Distributions
Description
Evaluation for density and distribution function of convolution of gamma
distributions in R. Two related exact methods and one approximate method are
implemented with efficient algorithm and C++ code. A quick guide for choosing
correct method and usage of this package is given in package vignette. For the
detail of methods used in this package, we refer the user to
Mathai(1982),
Moschopoulos(1984),
Barnabani(2017),
Hu et al.(2020).
