A new class of C 1 -smooth univariate cubic L 1 smoothing splines is introduced. The coefficients of these smoothing splines are calculated by minimizing the weighted sum of the 1 norm of the residuals of the data-fitting equations and the L 1 norm of the second derivative of the spline. Cubic L 1 s
