Dear all,

Anybody knows about the difference amongst various spline smoothers, specifically in R, 'bs' (by default a cubic spline), 'ns', smooth.spline with roughness penalty along with many other smoothers? I've consulted serveral books like 'S-plus Guide to Statistics' by Mathsoft, Ripley and Venables' Splus book and Eubank's Spline Smoothing, but I was still looking for a substantial discussion on the difference in using these smoothers. I try to put the question clear or maybe somebody can provide some sources for reference. If possible, I'd also like to see some comments for practice.

Regards,
LS
