sn (version 1.3-0)

The Skew-Normal and Skew-t Distributions

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 diagnostics, in the univariate and the multivariate case.
