In Section 2.1, we introduce the `ssr` function for general
smoothing spline regression models with one variable. In sections
2.2 to 2.4, we show how to use `ssr` to fit more complicated
models such as partial spline models, smoothing spline ANOVA
(SS ANOVA) models for correlated observations and/or
observations with unequal variances, and SS ANOVA models for data
from exponential families.
