Entropy of the Gompertz-Makeham mortality model [PDF]
Demographic Research, 2014 Background: Life table entropy is a quantity frequently used in demography; e.g., as a measure ofheterogeneity in age at death, or as the elasticity of life expectancy with regards to proportional changes in age-specific mortality.

The use of Gompertz models in growth analyses, and new Gompertz-model approach: An addition to the Unified-Richards family. [PDF]
PLoS ONE, 2017 The Gompertz model is well known and widely used in many aspects of biology. It has been frequently used to describe the growth of animals and plants, as well as the number or volume of bacteria and cancer cells.

Population modeling of tumor growth curves and the reduced Gompertz model improve prediction of the age of experimental tumors. [PDF]
PLoS Computational Biology, 2020 Tumor growth curves are classically modeled by means of ordinary differential equations. In analyzing the Gompertz model several studies have reported a striking correlation between the two parameters of the model, which could be used to reduce the ...

Inference on an heteroscedastic Gompertz tumor growth model
Mathematical Biosciences, 2020 We consider a non homogeneous Gompertz diffusion process whose parameters are modified by generally time-dependent exogenous factors included in the infinitesimal moments. The proposed model is able to describe tumor dynamics under the effect of anti-proliferative and/or cell death-induced therapies.

Diauxie Studies in Biogas Production from Gelatin and Adaptation of the Modified Gompertz Model: Two-Phase Gompertz Model [PDF]
Applied Sciences, 2021 The anaerobic degradation of gelatin results in a two-phase cumulative biogas production curve, i.e., diauxie behaviour. The modified Gompertz model is normally used to fit these curves but due to the diauxie it would result in a less accurate ...

On the Construction of Some Fractional Stochastic Gompertz Models [PDF]
Mathematics, 2020 The aim of this paper is the construction of stochastic versions for some fractional Gompertz curves. To do this, we first study a class of linear fractional-integral stochastic equations, proving existence and uniqueness of a Gaussian solution.
