Super-Gaussian vs. Gaussian distribution. A super-Gaussian distribution (Laplace distribution for example) has a more spiky peak and a longer tail than a Gaussian distribution. The distribution of a noiseless loading vector is similar to a super-Gaussian distribution. If a large amount of noise exists in the loading vectors, its distribution will tend towards a Gaussian distribution.
