Two Statistical Approaches to Justify the Use of the Logistic Function in Binary Logistic Regression

open access: yesMathematical Problems in Engineering, 2023
Logistic regression is a commonly used classification algorithm in machine learning. It allows categorizing data into discrete classes by learning the relationship from a given set of labeled data.

A note on Verhulst's logistic equation and related logistic maps [PDF]

open access: yes, 2010
We consider the Verhulst logistic equation and a couple of forms of the corresponding logistic maps. For the case of the logistic equation we show that using the general Riccati solution only changes the initial conditions of the equation.

CPAT: Coding-Potential Assessment Tool using an alignment-free logistic regression model

open access: yesNucleic Acids Research, 2013
Thousands of novel transcripts have been identified using deep transcriptome sequencing. This discovery of large and ‘hidden’ transcriptome rejuvenates the demand for methods that can rapidly distinguish between coding and noncoding RNA. Here, we present

Military Logistics vs. Business Logistics

open access: yesEconomic Analysis, 2021
Military logistics as a specific area of logistics management makes the difference between a well-supplied and self-sustainable army which due to an efficiently created supply chain, can perform it’s military actions more efficiently, and an army that, due to insufficient commitment to military logistics activities creates an inefficient army that is ...
