This example illustrates some properties of splines. Splines are curves, which are usually required to be continuous and smooth. Splines are usually defined as piecewise polynomials of degree n with ...

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 ...

Following work of Heindl and of Powell and Sabin, each triangle of an arbitrary (regular) triangulation $\Delta$ of a polygonal region $\Omega$ in $\Bbb R^2$ is subdivided into twelve triangles, using ...

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 ...
