Parametric equation
In mathematics, a parametric equation defines a group of quantities as functions of one or more independent variables called parameters. Parametric equations are commonly used to express the coordinates of the points that make up a geometric obj ...
, a representation of a curve through equations, as functions of a variable
*
Parametric statistics
Parametric statistics is a branch of statistics which assumes that sample data comes from a population that can be adequately modeled by a probability distribution that has a fixed set of parameters. Conversely a non-parametric model does not as ...
, a branch of statistics that assumes data has come from a type of probability distribution
*
Parametric derivative
In calculus, a parametric derivative is a derivative of a dependent variable with respect to another dependent variable that is taken when both variables depend on an independent third variable, usually thought of as "time" (that is, when the depen ...
, a type of derivative in calculus
*
Parametric model
In statistics, a parametric model or parametric family or finite-dimensional model is a particular class of statistical models. Specifically, a parametric model is a family of probability distributions that has a finite number of parameters.
Def ...
, a family of distributions that can be described using a finite number of parameters
*
Parametric oscillator, a harmonic oscillator whose parameters oscillate in time
*
Parametric surface A parametric surface is a surface in the Euclidean space \R^3 which is defined by a parametric equation with two parameters Parametric representation is a very general way to specify a surface, as well as implicit representation. Surfaces that occ ...
, a particular type of surface in the Euclidean space R

Parametric family
In mathematics and its applications, a parametric family or a parameterized family is a family of objects (a set of related objects) whose differences depend only on the chosen values for a set of parameters.
Common examples are parametrized (fam ...
, a family of objects whose definitions depend on a set of parameters
Science
*
Parametric process, in optical physics, any process in which an interaction between light and matter does not change the state of the material
*
Spontaneous parametric down-conversion, in quantum optics, a source of entangled photon pairs and of single photons
*
Optical parametric amplifier An optical parametric amplifier, abbreviated OPA, is a laser light source that emits light of variable wavelengths by an optical parametric amplification process. It is essentially the same as an optical parametric oscillator, but without the optic ...
, a type of laser light source that emits light of variable wavelengths

Statistical parametric mapping
Statistical parametric mapping (SPM) is a statistical technique for examining differences in brain activity recorded during functional neuroimaging experiments. It was created by Karl Friston. It may alternatively refer to software created by ...

Parametric determinism
Parametric determinism is a Marxist interpretation of the course of history. It was formulated by Ernest Mandel and can be viewed as one variant of Karl Marx's historical materialism or as a philosophy of history.
