# ConwayMaxwellPoissonDistribution

class ConwayMaxwellPoissonDistribution<Arg1, Arg2, Arg3>(λ:Arg1, ν:Arg2, n:Arg3) < BoundedDiscreteDistribution

Conway-Maxwell-Poisson distribution.

• 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 $O(n)$.
