Stability conditions of limit cycle for Gompertz Autoregressive model

open access: yesTikrit Journal of Pure Science, 2023
In this paper, we suggest Gompertz Autoregressive model by using the cumulative distribution function of Gompertz distribution and, the aim of this paper is studying and finding the stability conditions of a limit cycle for the Gompertz Autoregressive ...

Generalized Gompertz - Generalized Gompertz Distribution

open access: yesJournal of Physics: Conference Series, 2019
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

open access: yesCzech Journal of Food Sciences, 2002
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

Solutions for better fitting Sigmoid-shaped functions to binary data [PDF]

open access: yesComputational Ecology and Software, 2020
Sigmoid-shaped curves are often used to estimate the probability of individuals surviving or becoming fecund (response: y) given some characteristic like age or size (predictor: x).

On Characterization of Gompertz Distribution by Properties of Generalized Record Values [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2014
In this chapter, we derive some recurrence relations satisfied by single and product moments of generalized record values arising from Gompertz and inverted Gompertz distributions.

Improvement of biomethane potential of sewage sludge anaerobic co-digestion by addition of “sherry-wine” distillery wastewater [PDF]

open access: yes, 2020
Co-digestion of sewage sludge (SS) with other unusually treated residues has been reported as an efficient method to improve biomethane production. In this work, Sherry-wine distillery wastewater (SWDW) has been proposed as co-substrate in order to ...

The Beta-Gompertz Distribution

open access: yesRevista Colombiana de Estadística, 2014
In this paper, we introduce a new four-parameter generalized version of the Gompertz model which is called Beta-Gompertz (BG) distribution. It includes some well-known lifetime distributions such as beta-exponential and generalized Gompertz distributions as special sub-models.

The Kumaraswamy Gompertz Distribution [PDF]

open access: yesJournal of Data Science, 2021
We introduce the four-parameter Kumaraswamy Gompertz distribution. We obtain the moments, generating and quantilefunctions, Shannon and R'enyi entropies, mean deviations and Bonferroni and Lorenz curves. We provide a mixture representation for the density function of the order statistics.
