logistic curve
11logistic function — noun A function, the result of the division of two exponential functions, that gives rise to the logistic curve …
12logistic growth — The logistic curve y = k/(1 ea+bx), with b < 0, has an S type form of slow (linear) growth, followed by exponential growth which slows to a stable level. Most physical and social growth follows this pattern, including industrial growth,… …
13Logistic map — The logistic map is a polynomial mapping of degree 2, often cited as an archetypal example of how complex, chaotic behaviour can arise from very simple non linear dynamical equations. The map was popularized in a seminal 1976 paper by the… …
14curve — 1. A nonangular continuous bend or line. 2. A chart or graphic representation, by means of a continuous line connecting individual observations, of the course of a physiologic activity, of the number of cases of a disease in a given period, or of …
15Generalised logistic function — The generalized logistic curve or function, also known as Richards curve is a widely used and flexible sigmoid function for growth modelling, extending the well known logistic curve.:Y = A + { K over (1 + Q e^{ B (t M)}) ^ {1 / u} }where Y =… …

17Hubbert curve — The Hubbert curve projects the rate of oil production over time, and is the main component of Hubbert peak theory. It was first proposed by geophysicist M. King Hubbert in the mid 1950s during his tenure at the Shell Oil Company. [cite journal |… …
18Species-area curve — The species area relationship for a contiguous habitat In ecology, a species area curve is a relationship between the area of a habitat, or of part of a habitat, and the number of species found within that area. Larger areas tend to contain… …
