On spline-on-spline numerical integration formula [PDF]

open access: yesJournal of Approximation Theory, 1989
In the paper is considered an application of the spline-on-spline interpolation to a numerical integration of the form \[ \int^{x_{j+1}}_{x_ j}f(x)dx\quad or\quad (\int^{x_{j+1}}_{x_ j}f(x)dx)/(\int^{1}_{0}f(x)dx) \] where \(j=0,1,...,n-1\). It is shown that an integral of the spline-on-spline interpoland gives better results than the spline itself ...

The use of spline-on-spline for the approximation of Cauchy principal value integrals

open access: yesApplied Mathematics and Computation, 1996
The use of spline-on-spline approximations to estimate Cauchy principal value integrals and their derivatives is discussed. Better results than those obtained by differentiating traditional single spline approximations might be expected. Unfortunately, the proofs of convergence (Theorems 3.2, 3.3) appear to be flawed because of the assumption of ...

COMPARISON OF B-SPLINE AND TRUNCATED SPLINE REGRESSION MODELS FOR TEMPERATURE FORECAST

open access: yesBarekeng, 2023
The spline regression model is a nonparametric model and it is applied to data that do not have a certain curve shape and do not have information about it.

Simulation and Verification of Involute Spline Tooth Surface Wear before and after Carburizing Based on Energy Dissipation Method

open access: yesMachines, 2023
This work studies the tooth surface wear of floating involute spline couplings. Based on the energy dissipation method, this study takes the floating involute spline couplings as the research object, divides the whole wear cycle into three wear stages ...

Efficient and direct estimation of the variance–covariance matrix in EM algorithm with interpolation method [PDF]

open access: yes, 2021
The expectation–maximization (EM) algorithm is a seminal method to calculate the maximum likelihood estimators (MLEs) for incomplete data. However, one drawback of this algorithm is that the asymptotic variance–covariance matrix of the MLE is not ...
