In probability theory and statistics, the poly-Weibull distribution is a continuous probability distribution.

In probability and statistics, the Gamma/Gompertz distribution is a continuous probability distribution.

In probability theory and statistics, the Weibull distribution is a continuous probability distribution.

In probability theory and statistics, the Weibull distribution is a continuous probability distribution.

In probability and statistics, the Gamma/Gompertz distribution is a continuous probability distribution.

If X has a Gumbel distribution, then the conditional distribution of Y=-X given that Y is positive, or equivalently given that X is negative, has a Gompertz distribution.

If X {\displaystyle X} has a Gumbel distribution, then the conditional distribution of Y=−X given that Y is positive, or equivalently given that X is negative, has a Gompertz distribution.

Authors who reject the validity of the Gompertz function after age 85 attribute the divergence to a heterogeneity effect and individual adaptation to life stress.

Says Buffelstein: “Research has shown that the chance of dying for mammals such as humans, horses and mice, among others, increases exponentially with age, according to the Gompertz law.

Since Gompertz’s law in the 19th century which states that the mortality rate increases exponentially with age, the question arises as to the existence of a mortality plateau after a certain age.
