Risk measurement of China's green financial market based on B-spline quantile regression [PDF]

open access: yesHeliyon, 2023
To accurately measure the spillover effect of China's green financial carbon emission market, a new measurement of conditional value at risk (CoVaR) based on the B-spline quantile methods is proposed.

A Best-Fitting B-Spline Neural Network Approach to the Prediction of Advection–Diffusion Physical Fields with Absorption and Source Terms [PDF]

open access: yesEntropy
This paper proposed a two-dimensional steady-state field prediction approach that combines B-spline functions and a fully connected neural network. In this approach, field data, which are determined by corresponding control vectors, are fitted by a ...

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

Quadratic B-Spline Surfaces with Free Parameters for the Interpolation of Curve Networks

open access: yesMathematics, 2022
In this paper, we propose a method for constructing spline surfaces interpolating a B-spline curve network, allowing the presence of free parameters, in order to model the interpolating surface.
