Discrete Gompertz Equation and Model Selection Between Gompertz and Logistic Models
International Journal of Forecasting, 2021Abstract A discrete Gompertz model and model selection between the Gompertz and logistic models are proposed. The proposed method utilizes the difference between the regression equations for the proposed and the discrete logistic models. The difference is whether the log of both sides is taken or not.

Parameter Estimation of the Gompertz Population
Biometrical Journal, 1997AbstractThe Gompertz distribution has been used to model human mortality and fit actuarial tables. In the recent years, this distribution has been studied by some authors. The MLE estimates for the parameters of the Gompertz distribution were disucssed by GARG, RAO and REDMOND (1970). The purpose of this paper is to develop an exact confidence interval

Journal of the Operational Research Society, 1994
In this paper, a simple Gompertz curve-fitting procedure is proposed. Its advantages include the facts that the stability of the saturation level over the sample period can be checked, and that no knowledge of its value is necessary for forecasting. An application to forecasting the stock of cars in the Netherlands illustrates its merits.

Gompertz in Context: The Gompertz and Related Distributions
2001A model often used in mortality analysis and forecasting is the Gompertz model. The model is attractive because the mathematical specification is consistent with theories of ageing. Other models that are used less often share some of the useful features of the Gompertz model. Furthermore, the Gompertz can be approached as a member of families of models

Gompertz curves, allometry and embryogenesis
The Bulletin of Mathematical Biophysics, 1970A number of new properties of the Gompertz curve are derived. In particular, the curve is shown to be of particular importance in the theory of biological similitude, because of a direct relation to the allometric law. A discussion is included indicating some of the practical limitations of the theory.
