checklink

Set the Right Link Function for Specified Parameter and Distribution

Description

This function is used within the distribution family specification of a GAMLSS model to define the right link for each of the parameters of the distribution. This function should not be called by the user unless he/she specify a new distribution family or wishes to change existing link functions in the parameters.

Usage

checklink(which.link = NULL, which.dist = NULL, link = NULL, link.List = NULL)

Arguments

`which.link`	which parameter link e.g. `which.link="mu.link"`
`which.dist`	which distribution family e.g. `which.dist="Cole.Green"`
`link`	a repetition of `which.link` e.g. `link=substitute(mu.link)`
`link.List`	what link function are required e.g. `link.List=c("inverse", "log", "identity")`

Value

Defines the right link for each parameter
