coef.gamlss: 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 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.
