WebApr 4, 2009 · In mathematics, a Gaussian function (named after Carl Friedrich Gauss) is a function of the form: for some real constants a > 0, b, c > 0, and e ≈ 2.718281828 ( Euler's number ). The graph of a Gaussian is a characteristic symmetric "bell shape curve" that quickly falls off towards plus/minus infinity. The parameter a is the height of the ...

It is a generalization to random vectors of the Student's t -distribution, which is a distribution applicable to univariate random variables.

Gaussian beams are usually (and also in this article) considered in situations where the beam divergence is relatively small (i.e., the beam waist radius sufficiently large), so that the so-called paraxial approximation can be applied. This approximation allows … reg winland state farmWebThe Student-t copula is an elliptical copula defined as: where n (the number of degrees of freedom) and r (linear correlation coefficient) are the parameters of the copula. When the number of degrees of freedom n is large (around 30 or so), the copula converges to the Normal copula just as the Student distribution converges to the Normal. reg winland state farm insuranceWebAn elliptical distribution displays affine equivariance ( 37.172 ), like the normal distribution does, however the distribution is not necessarily preserved by the transformation ( Alert 37.7 ).
