In gamlss: Generalized Additive Models for Location Scale and Shape

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, ... )
                      
coefAll(obj, deviance = FALSE, ...)

Arguments

object, obj	a GAMLSS fitted model
what	which parameter coefficient is required, default what="mu"
parameter	equivalent to what (more obvious name)
deviance	whether to print also the deviance.
...	for extra arguments

Value

Coefficients extracted from the GAMLSS model object.
