The Demmler–Reinsch basis is not effective for smoothing splines because smoothing splines have too many knots. For P-splines, however, the Demmler–Reinsch basis is very useful for super-fast generalized cross-validation.

WebMar 6, 2024 · In the GAM approach, it makes sense to start with a highly flexible approach and then apply penalties to achieve the smoothness required for a plausible shape. While fitting GAMs, I always use P-spline (=penalized B-splines). However, S.
