Web'The book provides a rather complete unified treatment of smoothing splines, starting with the classical polynomial smoothing spline, and including the periodic smoothing spline on … WebCubic splines tend to be poorly behaved at the two tails (before the first knot and after the last knot). To avoid this, restricted cubic splines are used. A r estricted cubic spline is a cubic spline in which the splines are constrained to be linear in the two tails. This generally provides a better fit to the data, and also has
