Normal distribution vs skewed distribution

The exponentially modified normal distribution is another 3-parameter distribution that is a generalization of the normal distribution to skewed cases. The skew normal still has a normal-like tail in the direction of the skew, with a shorter tail in the other direction; that is, its density is asymptotically proportional to for some positive . Thus, in terms of the seven states of randomness, it shows "proper mild randomness". In contrast, the exponentially modified normal has an expon… Web5 de mar. de 2011 · Skewness is a measure of symmetry, or more precisely, the lack of symmetry.
