WebFigure:Skewness of a distribution measures how asymmetric the distribution is. In this example, the skewness are: orange = 0.8943, black = 0, blue = -1.414. 12/22 Weberf(z) is the "error function" encountered in integrating the normal distribution (which is a normalized form of the Gaussian function). It is an entire function defined by erf(z)=2/(sqrt(pi))int_0^ze^(-t^2)dt.
