sn (version 1.5-2)

The Skew-Normal and Related Distributions Such as the Skew-t

Description

Build and manipulate probability distributions of the skew-normal family and some related ones, notably the skew-t family, and provide related statistical methods for data fitting and model diagnostics, in the univariate and the multivariate case.
