The standard logistic function is the logistic function with parameters =, =, =, which yields = + = + = / / + /.In practice, due to the nature of the exponential function, it is often sufficient to compute the standard logistic function for over a small range of real numbers, such as a range contained in [−6, +6], as it quickly converges very close to its saturation values of 0 and 1.

The following graph shows the mean number of edits per article, and is intended as a measure of the quality of the articles, assuming that editing improves the content. The graph is plotted in logarithmic scale, and this data also fits well with exponential growth starting from October 2002.
English: Figure 1 shows the growth of a population following a logistic curve, resulting in the S-shaped graph. This model reaches a stable equilibrium, sustaining the population at the carrying capacity as time continues.
Although growth may initially be exponential, the modelled phenomena will eventually enter a region in which previously ignored negative feedback factors become significant (leading to a logistic growth model) or other underlying assumptions of the exponential growth model, such as continuity or instantaneous feedback, break down.
Logistic growth is an example for a bounded growth which is limited by saturation: The graph shows an imaginary market with logistic growth. In that example, the blue curve depicts the development of the size of that market. The red curve describes the growth of such a market as the first derivative of the market volume. The yellow curve ...

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.
