Webof Eilers and Marx (1996), penalized spline estimators (or penalized splines for short) have gained much popularity and have become a standard general-purpose method for function estimation. Many applications of penalized splines are presented in the mono-graph Ruppert, Wand and Carroll (2003). As an indication of popularity of penalized 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. Wood recommend to use the penalized thin-plate spline as it tends to give the best MSE performance.
