KNOT OPTIMIZATION FOR BI-RESPONSE SPLINE NONPARAMETRIC REGRESSION WITH GENERALIZED CROSS-VALIDATION (GCV)

open access: yesBarekeng
Nonparametric regression is a statistical method used to model relationships between variables without making strong assumptions about the functional form of the relationship.

Robust generalized cross-validation for choosing the regularization parameter [PDF]

open access: yesInverse Problems, 2006
Let fλ be the regularized solution for the problem of estimating a function or vector f0 from noisy data yi ≤ Lif0 + ei, i ≤ 1, ..., n, where Li are linear functionals. A prominent method for the selection of the crucial regularization parameter λ is generalized cross-validation (GCV). It is known that GCV has good asymptotic properties as n → ∞ but it

Generalized cross validation for wavelet thresholding

open access: yes, 1995
oisy data are often fitted using a smoothing parameter, controling the importance of two objectives that are opposite to a certain extend. One of these two is smoothness and the other is closeness to the input data. The optimal value of this paramater minimizes the error of the result (as compared to the unknown, exact data), usually expressed in the ...

Nonparametric Spline Truncated Regression with Knot Point Selection Method Generalized Cross Validation and Unbiased Risk

open access: yesJTAM (Jurnal Teori dan Aplikasi Matematika), 2023
Nonparametric regression approaches are used when the shape of the regression curve between the response variable and the predictor variable is assumed to be unknown. Nonparametric excess regression has high flexibility.

Relationship between Engraulis japonicus Resources and Environmental Factors Based on Multi-Model Comparison in Offshore Waters of Southern Zhejiang, China

open access: yesJournal of Marine Science and Engineering, 2022
In order to accurately explore the relationship between the density of Engraulis japonicus and environmental factors, five types of models, including Tweedie-Generalized Additive Model (GAM), two-stage GAM, Ad hoc-GAM, and Generalized Additive Mixing ...

Exploring the Link Between Additive Heritability and Prediction Accuracy From a Ridge Regression Perspective

open access: yesFrontiers in Genetics, 2020
Genome-Wide Association Studies (GWAS) explain only a small fraction of heritability for most complex human phenotypes. Genomic heritability estimates the variance explained by the SNPs on the whole genome using mixed models and accounts for the many ...

Goodness of Fit Test of an Autocorrelated Time Series Cubic Smoothing Spline Model

open access: yesJournal of Nigerian Society of Physical Sciences, 2021
We investigated the finite properties as well as the goodness of fit test for the cubic smoothing spline selection methods like the Generalized Maximum Likelihood (GML), Generalized Cross-Validation (GCV) and Mallow CP criterion (MCP) estimators for time-
