represents a Gompertz distribution with scale parameter λ and frailty parameter ξ.
represents a Gompertz–Makeham distribution with parameters λ, ξ, θ, and α.
- The hazard function for value in a Gompertz distribution is given by for , and is zero for .
- The hazard function for value in a Gompertz–Makeham distribution is given by for and is zero for .
- GompertzMakehamDistribution allows λ and ξ to be any positive real numbers and θ and α any non–negative real numbers.
- GompertzMakehamDistribution can be used with such functions as Mean, CDF, and RandomVariate.
