In [[probability]] and [[statistics]], an '''elliptical distribution''' is any member of a broad family of [[probability distribution]]s that generalize the [[multivariate normal distribution]] and inherit some of its properties.

			==Definition==
			Elliptical distributions can be defined using [[characteristic function (probability theory)\|characteristic function]]s. A multivariate distribution is said to be '''elliptical''' if its characteristic function is of the form<ref name=chs>{{cite journal\|
			author=Stamatis Cambanis, Steel Huang, and Gordon Simons\| title=On the Theory of Elliptically Contoured Distributions\|journal= Journal of Multivariate Analysis\| volume=11\| year=1981\| pages=368–385}}</ref>

			:<math>e^{it'\mu} \Psi(t' \Sigma t) \, </math>
			for a specified vector <math>\mu</math>, positive-definite matrix <math>\Sigma</math>, and characteristic function <math>\Psi</math>. The function <math>\Psi</math> is known as the '''characteristic generator''' of the elliptical distribution.<ref>Härdle and Simar (2012), p. 178.</ref>

			Elliptical distributions can also be defined in terms of their [[density function]]s. When they exist, the density functions ''f'' have the structure:
			:<math>f(x)= k \cdot g((x-\mu)'\Sigma^{-1}(x-\mu))</math>
			where <math>k</math> is the scale factor, <math>x</math> is an <math>n</math>-dimensional random vector with median vector <math>\mu</math> (which is also the mean vector if the latter exists), <math>\Sigma</math> is a [[positive definite matrix]] which is proportional to the [[covariance matrix]] if the latter exists, and <math>g</math> is a function mapping from the non-negative reals to the non-negative reals giving a finite area under the curve.

			==Properties==
			In the 2-dimensional case where the density exists, each iso-density locus (the set of ''x<sub>1</sub>,x<sub>2</sub>'' pairs all giving a particular value of <math>f(x)</math>) is an [[ellipse]] (hence the name elliptical distribution). More generally, for arbitrary ''n'' the iso-density loci are [[ellipsoid]]s.

			The [[multivariate normal distribution]] is the special case in which <math>g(z)=e^{-z/2}</math> for quadratic form <math>z</math>. While the multivariate normal is unbounded (each element of <math>x</math> can take on arbitrarily large positive or negative values with non-zero probability, because <math>e^{-z/2}>0</math> for all non-negative <math>z</math>), in general elliptical distributions can be bounded or unbounded—such a distribution is bounded if <math>g(z)=0</math> for all <math>z</math> greater than some value.

			Because the index variable ''x'' enters the density function quadratically, all elliptical distributions are [[Symmetric distribution\|symmetric]] about <math>\mu.</math>

			==Applications==
			Elliptical distributions are important in [[portfolio theory]] because, if the returns on all assets available for portfolio formation are jointly elliptically distributed, then all portfolios can be characterized completely by their location and scale – that is, any two portfolios with identical location and scale of portfolio return have identical distributions of portfolio return (Chamberlain 1983; Owen and Rabinovitch 1983). For multi-normal distributions, location and scale correspond to mean and standard deviation.
