Generalised 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 =… … Wikipedia
Generalised metric — In mathematics, the concept of a generalised metric is a generalisation of that of a metric, in which the distance is not a real number but taken from an arbitrary ordered field.In general, when we define metric space the distance function is… … Wikipedia

Error function — Plot of the error function In mathematics, the error function (also called the Gauss error function) is a special function (non elementary) of sigmoid shape which occurs in probability, statistics and partial differential equations. It is defined … Wikipedia
Binary function — In mathematics, a binary function, or function of two variables, is a function which takes two inputs. Precisely stated, a function f is binary if there exists sets X, Y, Z such that:,f colon X imes Y ightarrow Zwhere X imes Y is the Cartesian… … Wikipedia
Logistic function — A logistic function or logistic curve is the most common sigmoid curve. It modelsthe S curve of growth of some set P . The initial stage of growth is approximately exponential; then, as saturation begins, the growth slows, and at maturity, growth … Wikipedia
Sign function — In mathematics, the sign function is a mathematical function that extracts the sign of a real number. To avoid confusion with the sine function, this function is often called the signum function (after the Latin form of sign ).In mathematical… … Wikipedia

Functional equation (L-function) — In mathematics, the L functions of number theory are expected to have several characteristic properties, one of which is that they satisfy certain functional equations. There is an elaborate theory of what these equations should be, much of which … Wikipedia
