Web12. The terminology of splines can be confusing (at least I find it so) as exactly what people mean when they use "cubic spline", for example, depends on the type of cubic spline; we can have, for example, both cubic smoothing splines and cubic (penalised) regression splines. What I sketch below is taken from sections 5.1.2 and 5.2 of Wood (2024).
