kyphosis

Data on the results of a spinal operation "laminectomy" on children, to
correct for a condition called "kyphosis"; see Hastie and
Tibshirani (1990) for details

datasets

Functions for fitting and working with generalized
additive models, as described in chapter 7 of "Statistical Models in
S" (Chambers and Hastie (eds), 1991), and "Generalized Additive
Models" (Hastie and Tibshirani, 1990).
