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

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
