[R] GAMS and Knots

[Bert Gunter]

This is the "knotty" problem of overfitting/balancing variance and bias.
There is no easy answer, but one obvious place to look for words of wisdom
is the Hastie/Tibshirani book, "Generalized Additive Models," #43 in the
Chapman and Hall little green book series.  See especially Chapter 3.

Hi
I was wondering if anyone knew how to work out the number of knots that 
should be applied to each variable when using gams in the mgcv library?
Any help or references would be much appreciated.
Thanks
Kathryn Baldwin
