Normality assessment, few paradigms and use cases

open access: yesRomanian Journal of Laboratory Medicine, 2022
Background: The importance of applying the normality tests is underlined by the way of continuing the statistical protocol for numerical data within inferential statistics, respectively by the parametric or non-parametric tests that we will apply further

Non-parametric specification testing of non-nested econometric models [PDF]

open access: yes, 1994
We consider the non-nested testing prqblem of non-parametric regressions. We show that, when the regression functions are unknown under both the null and the alternative hypotheses, an extension of the J-test procedure of Davidson and Mackinnon (1981 ...

Genotype by environment interaction and yield stability in sugarcane

open access: yesRevista Facultad Nacional de Agronomía Medellín, 2017
Genotype by environment interaction (GEI) reduces the association between phenotype and genotype which result in relative ranking and stability differences of genotypes across environment.

High-Dimensional Statistics: Non-Parametric Generalized Functional Partially Linear Single-Index Model

open access: yesMathematics, 2022
We study the non-parametric estimation of partially linear generalized single-index functional models, where the systematic component of the model has a flexible functional semi-parametric form with a general link function.

Statistics of Extremes in Athletics

open access: yesRevstat Statistical Journal, 2011
TV shows on any athletic event make clear that those who want gold medals cannot dispense statistics. And the statistics more appealing to champions and coachers are the extreme order statistics, and in particular maximum (or minimum) values and records.

A Comparison of Nonparametric Statistics and Bootstrap Methods for Testing Two Independent Populations with Unequal Variance

open access: yesInternational Journal of Analysis and Applications, 2023
The common parametric statistics used for testing two independent populations have often required the assumptions of normality and equal variances. Nonparametric tests have been used when assumptions of parametric tests cannot be achieved.
