Local kernel nonparametric discriminant analysis for adaptive extraction of complex structures

Open Physics, 2017
The linear discriminant analysis (LDA) is one of popular means for linear feature extraction. It usually performs well when the global data structure is consistent with the local data structure.

Using a DEA Management Tool through a Nonparametric Approach: An Examination of Urban-Rural Effects on Thai School Efficiency

International Journal of Education Policy and Leadership, 2009
This paper examines urban-rural effects on public upper-secondary school efficiency in northern Thailand. In the study, efficiency was measured by a nonparametric technique, data envelopment analysis (DEA).

A nonparametric test of exogeneity [PDF]

, 2004
This paper is concerned with inference about a function g that is identified by a conditional moment restriction involving instrumental variables. The function is nonparametric. It satisfies mild regularity conditions but is otherwise unknown. The paper

Statistical testing frameworks for process efficiency and variability management [PDF]

Journal of Applied Research on Industrial Engineering
This study explores the comparative efficacy of parametric and nonparametric statistical tests in analyzing clinical metrics, specifically weight (Peso (Kg)), height (H), and Body Mass Index (BMI (kg/m²)) for Glucagon-like Peptide-1 (GLP1) and Sodium ...

On the existence of solutions to adversarial training in multiclass classification

European Journal of Applied Mathematics
Adversarial training is a min-max optimization problem that is designed to construct robust classifiers against adversarial perturbations of data. We study three models of adversarial training in the multiclass agnostic-classifier setting.

The Local Linear M-Estimation with Missing Response Data

Journal of Applied Mathematics, 2014
This paper studies the nonparametric regressive function with missing response data. Three local linear M-estimators with the robustness of local linear regression smoothers are presented such that they have the same asymptotic normality and consistency.

SAS/IML Macros for a Multivariate Analysis of Variance Based on Spatial Signs

Journal of Statistical Software, 2006
Recently, new nonparametric multivariate extensions of the univariate sign methods have been proposed. Randles (2000) introduced an affine invariant multivariate sign test for the multivariate location problem. Later on, Hettmansperger and Randles (2002)

Stacked survival models for residual lifetime data

BMC Medical Research Methodology, 2022
When modelling the survival distribution of a disease for which the symptomatic progression of the associated condition is insidious, it is not always clear how to measure the failure/censoring times from some true date of disease onset.
