Beta binomial and Beta negative binomial
Hi,
I need Beta binomial and Beta negative binomial functions but in R there is
only SuppDists package which provide this distributions using a limited

which provide a limited parameter space for Beta binomial and Beta negative
binomial functions (e.g. alpha + beta <1 in the Beta negative binomial).
I've done a checkout to R svn to seek the code for the implementation of
distribution functions (dbinom et al.) but I haven't s...
