In this article we introduce a smoothing spline estimate for fixed design regression estimation based on real and artificial data, where the artificial data comes from previously undertaken similar experiments. The smoothing spline estimate gives different weights to the real and the artificial data. It...

In several recent papers, the idea has been proposed of using implicit Runge-Kutta formulae for the approximate integration of non-linear two-point boundar... JR Cash - 《Computers & Mathematics with Applications》 被引量: 118发表: 1986年 CALCULATION OF THE SMOOTHING SPLINE WITH WEIGHTED ROUGHN...
We consider the problem of designing optimal smoothing spline curves and surfaces for a given set of discrete data. For constructing curves and surfaces, we employ normalized uniform B-splines as the basis functions. First we derive concise expressions for the optimal solutions in the form which ...
Extensive discussions are devoted to model construction, smoothing parameter selection, computation, and asymptotic convergence. Most of the computational and data analytical tools discussed in the book are implemented in R, an open-source clone of the popular S/S- PLUS language. Code for regression...

R smooth.spline 拟合平滑样条曲线R语言 smooth.spline 位于stats 包(package)。 说明 将三次平滑样条拟合到提供的数据。 用法 smooth.spline(x, y = NULL, w = NULL, df, spar = NULL, lambda = NULL, cv = FALSE, all.knots = FALSE, nknots = .nknots.smspl, keep.data = TRUE, df.offset ...
The path-smoothing algorithm interpolates a parametric cubic spline that passes through all input reference pose points. The parameter of the spline is the cumulative chord length at these points.[1] The tangent direction of the smoothed output path approximately matches the orientation angle of the...
I am trying to extract the fracture aperture from a tomography image. I have written the code for the extraction, and everything works using the fitting smoothing spline (createFit function attached) for clu_sli_12.mat and I_12.mat, but not on clu_s...
