Notes

The pdf is

skewnorm.pdf(x, a) = 2 * norm.pdf(x) * norm.cdf(a*x)

skewnorm takes a real number $a$ as a skewness parameter When a = 0 the distribution is identical to a normal distribution (norm). rvs implements the method of ^[1].

This distribution uses routines from the Boost Math C++ library for the computation of cdf, ppf and isf methods. ^[2]
