getSmo: Extracting Smoother information from a GAMLSS fitted object

In gamlss: Generalized Additive Models for Location Scale and Shape

Extracting Smoother information from a GAMLSS fitted object

Description

The function getSmo() extracts information from a fitted smoothing additive term.

Usage

getSmo(object, what = c("mu", "sigma", "nu", "tau"), 
       parameter= NULL, which = 1)

Arguments

object	a GAMLSS fitted model
what	which distribution parameter is required, default what="mu"
parameter	equivalent to what
which	which smoothing term i.e. 1, 2 etc. Note that 0 means all.

Details

This function facilitates the extraction of information from a fitted additive terms. For example getSmo(m1,"sigma",2) is equivalent of m1$sigma.coefSmo[[2]]. To get the actual fitted values type m1$sigma.s[[2]]

Value

A list containing information about a fitted smoother or a fitted objects
