WebbThe S-shaped logistic growth model has been extensively studied and applied to a wide range of biological and socio-technical systems. A model, the “Bi-logistic”, is presented for the analysis of systems that experience two phases … 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.
