Detailed Description

template<typename RealType>
struct skewed_distribution< RealType >

A distribution of values in range [0; 1] that are skewed towards 0.

The alpha parameter affects the factor of skewed-ness, with alpha = 1 causing a uniform distribution, alpha < 1 causing a skew towards 1, and alpha > 1 causing a skew towards 0.
