class ConwayMaxwellPoissonDistribution<Arg1, Arg2, Arg3>(λ:Arg1, ν:Arg2, n:Arg3) < BoundedDiscreteDistribution
- λ: Rate.
- ν: Dispersion.
- n: Truncation point.
The distribution is always truncated on [0,n] because of an intractable normalizing constant that can only be expressed as an infinite series on the support of the non-truncated distribution, [0,\infty). The larger n, the closer the approximation to the non-truncated distribution---if that is desired---but the more expensive operations: most are O(n).
