Extract Model Coefficients in a GAMLSS fitted model

Description

coef.gamlss is the GAMLSS specific method for the generic function coef which extracts model coefficients from objects returned by modelling functions. ‘coefficients’ is an alias for coef.

Usage

## S3 method for class 'gamlss'
coef(object, what = c("mu", "sigma", "nu", "tau"), 
                      parameter = NULL, ... )

Arguments

`object`	a GAMLSS fitted model
`what`	which parameter coefficient is required, default `what="mu"`
`parameter`	equivalent to `what` (more obvious name)
`...`	for extra arguments

Value

Coefficients extracted from the GAMLSS model object.
