Smoothing, splines and smoothing splines; Their application in geomagnetism
Journal of Computational Physics, 1988This paper is concerned with the application of spline smoothing in nonparametric regression on geomagnetic data. Some properties of well- known cubic smoothing splines and cubic least squares splines are discussed. It is asserted that in many important cases using smoothing splines is too expensive and least squares splines cannot model the data ...

SiZerSS is a shortening for ``Significant Zero crossing of derivatives for smoothing splines''. This is a 2D graphical display at which for a smoothing spline \(\hat f_\lambda(x)\) (\(\lambda\in[\lambda_{\min},\lambda_{\max}]\) being a smoothing parameter) a point with coordinates \((\lambda,x)\) is marked by its colour if \((\partial/\partial x ...

Spline Interpolation and Smoothing on Hyperspheres
SIAM Journal on Scientific Computing, 1994The authors generalize a result of \textit{G. Wahba} [SIAM J. Sci. Stat. Comput. 2, 5-16 (1981; Zbl 0537.65008)] concerning spline interpolation and smoothing on the two-dimensional sphere. Their generalizations are threefold. Firstly, Wahba's results are extended to arbitrary dimensional hyperspheres.

The author considers periodic and nonperiodic semi-local smoothing splines, called \(S\)-splines of class \(C^p\), generated by polynomials of degree \(n\). In the construction of such splines the first \(p+1\) coefficients of each underlying polynomial are determined by the values of the preceding polynomial and its first \(p\) derivatives at the knot

A simple smoothing spline, III
Computational Statistics, 1999This paper is the third in a series devoted to the study of linear smoothing splines; for the review of Part II see [Zbl 1057.62515]. The present article focuses on computational aspects with the specific goal of developing an in-depth understanding of the methods for computing the linear smoothing spline.

Variance Reduction in Smoothing Splines
Scandinavian Journal of Statistics, 2009Abstract. We develop a variance reduction method for smoothing splines. For a given point of estimation, we define a variance‐reduced spline estimate as a linear combination of classical spline estimates at three nearby points. We first develop a variance reduction method for spline estimators in univariate regression models.

Publisher Summary The chapter describes the methods, with some changes, that were used by the author to solve the numerical problem assigned to him at the Ballistics Research Laboratories in Aberdeen, Maryland, during the Second World War. The problem was to smooth very extended equidistant tables of drag functions (or drag coefficients) by ...

Parametric smoothing of spline interpolation
2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004Cubic spline interpolation is commonly applied in signal reconstruction problems. However, overshooting between samples is normally observed, and typically the reconstructed signal does not preserve the statistical properties of the original data or other desired properties such as monotonicity or convexity.
