+random-variate generation, and method-of-moments parameter-estimation
+functions for the Delaporte distribution with parameterization based on
+Vose (2008).  The Delaporte is a discrete probability distribution which can
+be considered the convolution of a negative binomial distribution with a
+Poisson distribution.  Alternatively, it can be considered a counting
+distribution with both Poisson and negative binomial components.  It has been
+studied in actuarial science as a frequency distribution which has more
+variability than the Poisson, but less than the negative binomial.")
