Parametric equation In mathematics, a parametric equation expresses several quantities, such as the coordinates of a point (mathematics), point, as Function (mathematics), functions of one or several variable (mathematics), variables called parameters. In the case ...

, a representation of a curve through equations, as functions of a variable *

Parametric statistics Parametric statistics is a branch of statistics which leverages models based on a fixed (finite) set of parameters. Conversely nonparametric statistics does not assume explicit (finite-parametric) mathematical forms for distributions when modeli ...

, 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. Defi ...

, 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 oc ...

, a particular type of surface in the Euclidean space R³ *

Parametric family In mathematics and its applications, a parametric family or a parameterized family is a indexed family, family of objects (a set of related objects) whose differences depend only on the chosen values for a set of parameters. Common examples are p ...

, a family of objects whose definitions depend on a set of parameters

* 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 Spontaneous parametric down-conversion (also known as SPDC, parametric fluorescence or parametric scattering) is a nonlinear instant optical process that converts one photon of higher energy (namely, a ''pump'' photon) into a pair of photons (name ...

, in quantum optics, a source of entangled photon pairs and of single photons * Optical parametric amplifier, 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 t ...

, a statistical technique for examining differences in brain activity recorded during functional neuroimaging * Parametric search

Parametric insurance Parametric insurance (also called index-based insurance) is a non-traditional insurance product that offers pre-specified payouts based upon a trigger event. Trigger events depend on the nature of the parametric policy and can include environmenta ...

, insurance that agrees to make a payment upon the occurrence of a triggering event * Parametric feature based modeler, a modeler using features defined to be parametric shapes associated with attributes

Computing

Parametric polymorphism In programming languages and type theory, parametric polymorphism allows a single piece of code to be given a "generic" type, using variables in place of actual types, and then instantiated with particular types as needed. Parametrically polymorph ...

, a feature of some type systems in computer programming * Parametric animation, a computer-animation technique *

Parametric Technology Corporation PTC Inc. (formerly Parametric Technology Corporation) is an American computer software and services company founded in 1985 and headquartered in Boston, Massachusetts. The company was a pioneer in parametric, associative feature-based, solid com ...

, an American technology company * Software parametric models, a set of related mathematical equations that incorporates variable parameters

Other uses

* Parametric feature based modeler, a modeler using features defined to be parametric shapes associated with attributes *

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. In an article critical of the ...

, a Marxist interpretation of the course of history *

Parametric equalizer Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer. Most hi-fi eq ...
