fitted.gamlss {gamlss}

Extract Fitted Values For A GAMLSS Model

Description

fitted.gamlss is the GAMLSS specific method for the generic function fitted which extracts fitted values for a specified parameter from a GAMLSS objects. fitted.values is an alias for it. The function fv() is similar to fitted.gamlls() but allows the argument what not to be character

Usage

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

Arguments

object

a GAMLSS fitted model

obj

a GAMLSS fitted model

what

which parameter fitted values are required, default what="mu"

parameter

equivalent to what

...

for extra arguments

Value

Fitted values extracted from the GAMLSS object for the given parameter.
