Azzalini's Skew-Normal   QuickTime movie (800K)


This animation shows Azzalini's varies between 0 (a standard Normal pdf) and 1 (a half-Normal pdf). Computational details are discussed on p.225 of Mathematical Statistics with Mathematica. For detail on skew densities, please see The Skew-Normal Web Site.


The following diagram plots the Azzalini skew-Normal pdf on a Pearson diagram. The diagram itself is derived as an exercise on p.185 of Mathematical Statistics with Mathematica.
