Updated citations in this pacakge.
Modified autoconf by CRAN’s suggestions.
coga:::dcoga_salvo for research purpose (Di Salvo, 2008).Rewrite function dcoga2dim and pcoga2dim to make it faster and more robust.
Rewrite function dcoga to make it can handle wider ranges of parameters and x.
Add new function dcoga_approx and pcoga_approx for approximation method, that can impove the speed of code under three or more variables case.
Remove microbenchmark from Suggests according to the requirement from CRAN.
Move vignette to inst in order to pass the cran check with devel R.
Rename variable sun to starn, in order to meet the requirement of solaris.
Remove RcppGSL from import.
Create ‘coga.h’ and ‘coga_RcppExports.h’ to make C++ code can be called directly.
Modify parameter shape and rate recycling work. When the length of one parameter is not a multiple of another, dcoga, pcoga, and rcoga will return a warning.
Add functions, dcoga2dim, and pcoga2dim, in order to achieve higher performance under situation of convolution of two gamma distributions.
Add function, pcoga2dim_diff_shape, in order to implementing the recurrence identity of shape parameter of convolution of two gamma distributions distribution function.
Update CRAN URL and BugReport URL from bitbucket to github.
Update Vignette.
dcoga for density function of convolution of gamma distributions, pcoga for distribution function of convolution of gamma distributions, and rcoga for simulating sample from convolution of gamma distributions.
