gamlss.dist (version 4.3-4)

gamlss.dist-package: The GAMLSS distributions

Description

This package contains all distributions to be used for GAMLSS models. Each distributions has its probability function, d, its commutative probability function, p, the inverse of the commutative probability function, q, its random generation function, r, and also the gamlss.family generating function

ll{ Package: gamlss.dist Type: Package Version: 1.5.0 Date: 2006-12-13 License: GPL (version 2 or later) } This package is design to be used with the package gamlss but the d, p, q and r functions can be used separately.
