A logical analysis of null hypothesis significance testing using popular terminology

open access: yesBMC Medical Research Methodology, 2022
Background Null Hypothesis Significance Testing (NHST) has been well criticised over the years yet remains a pillar of statistical inference. Although NHST is well described in terms of statistical models, most textbooks for non-statisticians present the

Hypothesis testing based on a vector of statistics [PDF]

open access: yesJournal of Econometrics, 2020
This paper presents a new approach to hypothesis testing based on a vector of statistics. It involves simulating the statistics under the null hypothesis and then estimating the joint density of the statistics. This allows the p-value of the smallest acceptance region test to be estimated.

The posterior probability of a null hypothesis given a statistically significant result [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2022
When researchers carry out a null hypothesis significance test, it is tempting to assume that a statistically significant result lowers Prob(H0), the probability of the null hypothesis being true.

Hypothesis-testing-based Range Statistical Resolution Limit of Radar

open access: yesLeida xuebao, 2019
Resolution performance is an important performance criteria of the radar systems. Typically, the Ambiguity Function (AF) of signals is used to define the range and Doppler limits. In this study Some new opinions are proposed—First, the AF is based on the

OS-PCA: Orthogonal Smoothed Principal Component Analysis Applied to Metabolome Data

open access: yesMetabolites, 2021
Principal component analysis (PCA) has been widely used in metabolomics. However, it is not always possible to detect phenotype-associated principal component (PC) scores.

STATISTICAL HYPOTHESIS TESTING USING FUZZY LINGUISTIC VARIABLES [PDF]

open access: yesFiabilitate şi Durabilitate, 2012
This work proposes a fuzzy statistical test of fuzzy hypotheses usinglinguistic variables. The method is based on Zadeh’s principle: the fuzzy population mean in the null hypothesis is converted to fuzzy numbers using conversion scales proposed by Chen ...

Testing Point Null Hypothesis of a Normal Mean and the Truth: 21st Century Perspective [PDF]

open access: yes, 2016
Testing a point (sharp) null hypothesis is arguably the most widely used statistical inferential procedure in many fields of scientific research, nevertheless, the most controversial, and misapprehended.
