P-splines have been introduced by Eilers and Marx (1996) as flexible smoothing procedures combining B-spline bases (see e.g. de Boor, 1978) and difference penalties. Suppose to observe a set of data {x,y}j=1ni where the vector x indicates the independent variable (e.g. time) and y...
Fast Bivariate Penalized Splines: the Sandwich Smoother We propose a fast penalized spline method for bivariate smoothing. Univariate P-spline smoothers are applied simultaneously along both co-ordinates. The ne... L Xiao,Y Li,D Ruppert - 《Journal of the Royal Statistical Society》 被引量: 73...
Approximation properties of the Wr,p-splines are studied and error bounds in terms of the mesh size ¦ E ¦ are calculated. Restricting ourselves to the case p = 2 and to quasiuniform partitions E, the second integral relation is proved and better error bounds in terms of ¦ E ¦...
The library also offers construction of penalized splines (P-splines). Figure: Illustration of a bicubic B-spline generated with the SPLINTER library. Sharing SPLINTER is the result of several years of development towards a fast and general library for multivariate function approximation. The initial...

The Script is mostly self-explanatory. You just have to pick a Pflow source and press the "Generate Splines" button. You can additionally choose to "fade" the Splines after x frames. This will help to vanish the splines when the particles are dead. ...
