Computational methods are presented for spline smoothing that make it practical to compute smoothing splines of degrees other than just the standard cubic case. Specifically, an order n algorithm is ...
You can use PROC TRANSREG to output to a SAS data set the same smoothing splines that the GPLOT procedure creates. The SMOOTH transformation is a noniterative transformation for smoothing splines. The ...
Quantile smoothing splines were introduced by Koenker, Ng and Portnoy as natural and appealing estimates of conditional quantiles of response variables. The natural setting for the problem considers ...
where belongs to the set of all continuously differentiable functions with square integrable second derivatives, and is a positive constant. Note The computations for a thin-plate smoothing spline are ...
