AbstractIn 1825 British actuary Benjamin Gompertz made a simple but important observation that a law of geometrical progression pervades large portions of different tables of mortality for humans. The simple formula he derived describing the exponential rise in death rates between sexual maturity and old age is commonly referred to as the Gompertz ...

Gompertz-power series distributions [PDF]
In this paper, we introduce the Gompertz power series class of distributions which is obtained by compounding Gompertz and power series distributions. This distribution contains several lifetime models such as Gompertz-geometric, Gompertz-Poisson, Gompertz-binomial, and Gompertz-logarithmic distributions as special cases.

Generalized Gompertz - Generalized Gompertz Distribution
In the present paper, we introduce a new generated family of continuous distributions based on generalized Gompertz distribution. Then generalized Gompertz - generalized Gompertz distribution is proposed as a special case of this new family. The probability density, cumulative distribution, reliability and hazard rate functions are introduced ...

The conformability of two equations for bacterial growth in pork
Pork is now distributed as cut meat, which increases the chance of contamination with bacteria. The rate of bacterial growth can be expressed by an exponential function. In order to find how the number of contaminating bacteria increases, we compared two
