%description
Three distinct methods are implemented for evaluating the sums of
arbitrary negative binomial distributions. These methods are: Furman's
exact probability mass function (Furman (2007)
<doi:10.1016/j.spl.2006.06.007>), saddlepoint approximation, and a method
of moments approximation. Functions are provided to calculate the density
function, the distribution function and the quantile function of the
convolutions in question given said evaluation methods. Functions for
generating random deviates from negative binomial convolutions and for
directly calculating the mean, variance, skewness, and excess kurtosis of
said convolutions are also provided.
