WitrynaA logistic growth curve is S-shaped. Populations that have a logistic growth curve will experience exponential growth until their carrying capacity is reached, at which point their growth begins to level. An exponential growth curve is J-shaped. Exponential growth is more common in R-selected species, which have a short life span and a … 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 in 1959.

Witryna6 maj 2024 · The J curve, or exponential growth curve, is one where the growth of the next period depends on the current period’s level and the increase is exponential.
