Description Usage Arguments See Also Examples

These functions provide information about the double Poisson
distribution with parameters `m`

and `s`

: density,
cumulative distribution, quantiles, and random generation.

The double Poisson distribution with `mu`

*= m* has density

*p(y) = c(m,s) s^(y/m) (m/y)^(y log(s)) y^(y-1) / y!*

for *y = 0, …*, where c(.) is a normalizing constant.
