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.

NON-PARAMETRIC STATISTICS [PDF]

open access: yes, 1981
This chapter discusses non-parametric statistics. It discusses some additional uses of the χ 2 distribution. The chapter explains how to test the independence of two criteria of classification and how to test whether the population from which the sampling is done is normal.

Solar Probability Density Estimation Using Adaptive Parametric/Nonparametric Hybrid Model

open access: yesIEEE Access
The accurate estimation of solar irradiance probability distribution is essential when assessing the level of available solar resources and attempting to minimize the effect of solar power variability on power system planning.

Evaluation of statistical approaches for association testing in noisy drug screening data

open access: yesBMC Bioinformatics, 2022
Background Identifying associations among biological variables is a major challenge in modern quantitative biological research, particularly given the systemic and statistical noise endemic to biological systems.

A test for model specification of diffusion processes

open access: yes, 2008
We propose a test for model specification of a parametric diffusion process based on a kernel estimation of the transitional density of the process. The empirical likelihood is used to formulate a statistic, for each kernel smoothing bandwidth, which is ...

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.

Two-parametric fractional statistics models for anyons

open access: yes, 2014
In the paper, two-parametric models of fractional statistics are proposed in order to determine the functional form of the distribution function of free anyons.

Parametric Statistics and the General Linear Model

open access: yesSpreadsheets in Education, 2014
Too many students acquire statistical knowledge and techniques independent of each other. The purpose of this paper is to illustrate the many connections mathematically between parametric statistics and the General Linear Model.

Statistics of radiation at Josephson parametric resonance

open access: yes, 2011
Motivated by recent experiments, we study theoretically the full counting statistics of radiation emitted below the threshold of parametric resonance in a Josephson junction circuit.
