getSmo {gamlss} | R Documentation |
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 |
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
