A negative correlation between the final ceiling of the logistic curve and its slope, established long time ago via a simulation study, motivated this closer look at flattening the curve of COVID-19. The diffusion of the virus is analyzed with S-shaped logistic-curve fits on the 25 countries most affected in which the curve was more than 95% comple...

This work concerns the too-often mentioned flattening of the curve of COVID-19. The diffusion of the virus is analyzed with logistic-curve fits on the 25 countries most affected at the time of the writing and in which the diffusion curve was more than 95% completed. A negative correlation observed between the final number of infections and the slop...

Look-up tables and graphs are provided for determining the uncertainties during logistic fits, on the three parameters M, α and to describing an S-curve of the form: The uncertainties and the associated confidence levels are given as a function of the uncertainty on the data points and the length of the historical period. Correlations between these...

Instabilities associated with population growth can be simulated by putting the logistic growth curve in a discrete form. In contrast to the usual derivation of chaos, which can only explain instabilities at the top of the curve, this method can also account for fluctuations during the early phases of the niche-filling process. Precursors, a steep...

Nowadays most people in business are familiar with the application of logistic growth to the sale of products even if they ignore its mathematical formulation. They all use a bell-shaped curve to refer to a product’s life cycle. The corresponding S-curve, for a product’s cumulative sales, is also something with which they feel comfortable.

A learning-curve approach has been employed to study inventiveness in the computer industry. The appearance of new models as well as the appearance of new computer manufacturers have been following typical logistic S-curves over the last 26 years of computer history. Innovation seems to come in S-waves, and even though many of today's major manufac...
