Semilocal smoothihg S-splines [PDF]

open access: yesКомпьютерные исследования и моделирование, 2010
Semilocal smoothing splines or S-splines from class C p are considered. These splines consist of polynomials of a degree n, first p + 1 coefficients of each polynomial are determined by values of the previous polynomial and p its derivatives at the point

Novel Formulas for B-Splines, Bernstein Basis Functions, and Special Numbers: Approach to Derivative and Functional Equations of Generating Functions

open access: yesMathematics, 2023
The purpose of this article is to give relations among the uniform B-splines, the Bernstein basis functions, and certain families of special numbers and polynomials with the aid of the generating functions method.

D-splines: Estimating rate schedules using high-dimensional splines with empirical demographic penalties

open access: yesDemographic Research, 2021
Background: High-dimensional parametric models with penalized likelihood functions strike a good balance between bias and variance for estimating continuous age schedules from large samples. The penalized spline (P-spline) approach is particularly useful

Adaptive P-Splines for challenging filtering problems in biomechanics

open access: yesJournal of Biomechanics, 2023
Suppression of noise from recorded signals is a critically important data processing step for biomechanical analyses. While a wide variety of filtering or smoothing spline methods are available, the majority of these are not well suited for the analysis of signals with rapidly changing derivatives such as the processing of motion data for impact-like ...

The influence of hip revision stem spline design on the torsional stability in the presence of major proximal bone defects.

open access: yesPLoS ONE, 2023
BackgroundDespite the success of primary total hip arthroplasty, the number of revisions remains high. Infection, aseptic loosening, periprosthetic fractures and dislocations are the leading causes of hip revision. Current revision stem designs feature a

“Childhood Anemia in India: an application of a Bayesian geo-additive model”

open access: yesBMC Pediatrics, 2021
Background The geographical differences that cause anaemia can be partially explained by the variability in environmental factors, particularly nutrition and infections.

Quantile Regression in Space-Time Varying Coefficient Model of Upper Respiratory Tract Infections Data

open access: yesMathematics, 2023
Space-time varying coefficient models, which are used to identify the effects of covariates that change over time and spatial location, have been widely studied in recent years. One such model, called the quantile regression model, is particularly useful

Random regression analyses using B-splines to model growth of Australian Angus cattle

open access: yesGenetics Selection Evolution, 2005
Regression on the basis function of B-splines has been advocated as an alternative to orthogonal polynomials in random regression analyses. Basic theory of splines in mixed model analyses is reviewed, and estimates from analyses of weights of Australian ...

Comparison of selected splines for stem form modeling: A case study in Norway spruce

open access: yesAnnals of Forest Research, 2014
Natural cubic spline has been frequently used to represent stem forms, with other spline types rarely involved. Splines are a large class of functions and there are many other spline types which might serve that purpose.
