gamlss.tr.package: The GAMLSS Add On Package for Truncated Distributions
In gamlss.tr: Generating and fitting truncated (gamlss.family) distributions

Description Details Author(s) References Examples

The main purpose of this package is to allow the user of the GAMLSS models to fit truncated distributions.

Package:	gamlss.tr
Type:	Package
Version:	1.0
Date:	2005-11-21
License:	GPL (version 2 or later)

The user can take any gamlss.family and create a truncated version of it. Left, right and both sides truncation is allowed. For continuous distributions left truncation at 3 means that the random variable can take the value 3. For discrete distributions left truncation at 3 means that the random variable can take values from 4 onwards. This is the same for right truncation. Truncation at 15 for a discrete variable means that 15 and greater values are not allowed but for continuous variable it mean values greater that 15 are not allowed (so 15 is a possible value).
