Remarks
The logistic distribution can be used to model growth. In many processes, the growth is slow at the beginning, picks up in the middle, and slows down again when approaching a saturation point.
The logistic distribution has two parameters: a LocationParameter and a ScaleParameter.
Example
Population growth and the market share of a new product can both be modeled
using the logistic distribution.
