Survival analysis of an impulsive stochastic delay logistic model with Lévy jumps

open access: yesMathematical Biosciences and Engineering, 2019
This paper studies a stochastic delay logistic model with Lévy jumps and impulsive perturbations. We show that the model has a unique global positive solution.

Online Efficient Secure Logistic Regression based on Function Secret Sharing [PDF]

open access: yes, 2023
Logistic regression is an algorithm widely used for binary classification in various real-world applications such as fraud detection, medical diagnosis, and recommendation systems. However, training a logistic regression model with data from different parties raises privacy concerns.

Various Logistic Curves in SIS and SIR Models [PDF]

open access: yesEuropean Journal of Mathematics and Statistics, Vol.4(2023), 1-6, 2022
In our previous paper, the logistic curve of the removed number was derived from SIR and SEIR models in the case of the small basic reproduction number. In this paper, we derive various logistic curves of the removed, unsusceptible and infectious numbers respectively from SIS and SIR models in the case of small and large basic reproduction numbers.

Logistic regression models

open access: yesAllergologia et Immunopathologia, 2011
In the health sciences it is quite common to carry out studies designed to determine the influence of one or more variables upon a given response variable. When this response variable is numerical, simple or multiple regression techniques are used, depending on the case.

Perceptions of Autonomous Vehicles: A Case Study of Jordan

open access: yesWorld Electric Vehicle Journal, 2023
Technologies for automated driving have advanced rapidly in recent years. Autonomous Vehicles (AVs) are one example of these recent technologies that deploy elements such as sensors or processing units to assist the driver.

Endogeneity in Logistic Regression Models

open access: yesEmerging Infectious Diseases, 2005
To the Editor: Ethelberg et al. (1) report on a study of the determinants of hemolytic uremic syndrome resulting from Shiga toxin–producing Escherichia coli. The dataset is relatively small, and the authors use stepwise logistic regression models to detect small differences.

Logistic model for stock market bubbles and anti-bubbles [PDF]

open access: yes, 2017
Log-periodic power laws often occur as signatures of impending criticality of hierarchical systems in the physical sciences. It has been proposed that similar signatures may be apparent in the price evolution of financial markets as bubbles and the ...

Model fitting of the seasonal population dynamics of the soybean aphid, Aphis glycines Matsumura, in the field

open access: yesJournal of Integrative Agriculture, 2023
The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), is one of the greatest threats to soybean production, and both trend analysis and periodic analysis of its population dynamics are important for integrated pest management (IPM).

Mathematical modeling and through artificial neural networks of the Spirulina sp. growth in a photobioreactor with fluorescent light source and solid state lighting

open access: yesScientia Agropecuaria, 2013
The Gompertz and logistic mathematical models in the Spirulina sp. growth kinetics were evaluated and were compared with a modeling through Backpropagation Artificial Neural Networks (BP- ANN).
