full.score {mgcv} | R Documentation |
Evaluates GCV/UBRE score for a GAM, given smoothing
parameters. The routine calls gam.fit
to fit the model, and is
usually called by nlm
to optimize the smoothing parameters.
This is basically a service routine for gam
, and is not usually
called directly by users. It is only used in this context for GAMs fitted by
outer iteration (see gam.outer
) when the the outer method is
"nlm.fd"
(see gam.method
).
full.score(sp,G,family,control,gamma,pearson)
sp |
The logs of the smoothing parameters |
G |
a list returned by gam.setup |
family |
The family object for the GAM. |
control |
a list returned be gam.control |
gamma |
the degrees of freedom inflation factor (usually 1). |
pearson |
whether the GCV/UBRE score should be based on the Pearson statistic or the deviance. The deviance is usually preferable. |
The value of the GCV/UBRE score, with attribute "full.gam.object"
which is the full object returned by gam.fit
.
