Non Gaussian

(something requiring adjustment from the gaussian function)

Non Gaussian (NG) indicates divergence from the Gaussian Function. The Cosmic Microwave Background, for example is approximately gaussian, but at some level of detail, may diverge. This is currently expected, as a consequence of Inflation and as an explanation for the development of gas clouds, Galaxy Clusters, etc. This is known as Primordial Non-Gaussianity.
