Spline smoothing under constraints on derivatives
The paper deals with univariate smoothing splines with space constraints imposed on the solution function. Utilizing the \(B\)-spline representation the authors demonstrate how the original problem can be replaced by a stronger one which in turn can be formulated as the least squares approximation problem with linear constraints. An algorithm for computing a smoothing spline is included.
