The generalized logistic function or curve is an extension of the logistic or sigmoid functions. Originally developed for growth modelling, it allows for more flexible S-shaped curves. The function is sometimes named Richards's curve after F. J. Richards, who proposed the general form for the family of models ...

This is in contrast to the classical homogeneous-nucleation depended polymerization where the initial aggregation determines the lag phase of fibrillation kinetics.

A sigmoid function is a mathematical function having a characteristic "S"-shaped curve or sigmoid curve. A common example of a sigmoid function is the logistic function shown in the first figure and defined by the formula: Other standard sigmoid functions are given in the Examples section. In some fi… WebSep 10, 2024 · 2. Three-parameter models. Sigmoid regression models with three-parameters and upper asymptotes are fitted to many types of biological growth. The most widely used models are the logistic, Gompertz, and von Bertalanffy (see Appendix A for some common model versions of these), which are related and behave similarly.

The Gompertz curve or Gompertz function is a type of mathematical model for a time series, named after Benjamin Gompertz (1779–1865). It is a sigmoid function which describes growth as being slowest at the start and end of a given time period. The right-side or future value asymptote of the function is approached much more gradually by the curve than the left-side or lower valued asymptote. This is in contrast to the simple logistic function in which both asymptotes are appro…
