InverseGaussianDistribution

InverseGaussianDistribution[μ,λ] represents an inverse Gaussian distribution with mean μ and scale parameter λ.

InverseGaussianDistribution[μ,λ,θ] represents a generalized inverse Gaussian distribution with parameters μ, λ, and θ.

Examples

Create an inverse Gaussian distribution:

dist = InverseGaussianDistribution[1, 2]
(* InverseGaussianDistribution[1, 2] *)

Compute the mean:

Mean[InverseGaussianDistribution[3, 1]]
(* 3 *)
