The following example continues the analysis of the data set Measure to illustrate how you can use PROC TPSPLINE to fit a spline model with a higher-order penalty term. Spline models with high-order ...

In this paper we investigate spline wavelets on general triangulations. In particular, we are interested in C¹ wavelets generated from piecewise quadratic polynomials. By using the Powell-Sabin ...

Keep the number of knots small (usually less than ten, although you can specify more). A degree three spline with nine knots, one at each decile, can closely follow a large variety of curves. Each ...

Gaussian processes have recently become popular in the empirical learning community. They encompass many classical methods of statistics, e.g., radial basis functions or various splines, and are ...
