Giving less power to statistical power. [PDF]

open access: yesLab Anim
Researchers often need to justify their choice of sample size, particularly in fields such as animal and clinical research, where there are obvious ethical concerns about relying on too many or too few study subjects. The common approach is still to depend on statistical power calculations, typically carried out using simple ...

Statistical power: An historical introduction [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2007
Despite the funding agencies’ growing demands towards power analyses, we believe researchers are still not fully aware of the statistical power concept, of the possible benefits of power analysis in the planning phase and of the ways to increase the ...

Developmental Dyslexia, Reading Acquisition, and Statistical Learning: A Sceptic’s Guide

open access: yesBrain Sciences, 2021
Many theories have been put forward that propose that developmental dyslexia is caused by low-level neural, cognitive, or perceptual deficits. For example, statistical learning is a cognitive mechanism that allows the learner to detect a probabilistic ...

Impact of Misdiagnosis in Case-Control Studies of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

open access: yesDiagnostics, 2023
Misdiagnosis of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) can occur when different case definitions are used by clinicians (relative misdiagnosis) or when failing the genuine diagnosis of another disease (misdiagnosis in a strict sense).

On the Power of Statistical Zero Knowledge [PDF]

open access: yesSIAM Journal on Computing, 2017
We examine the power of statistical zero knowledge proofs (captured by the complexity class $\mathsf{SZK}$) and their variants. First, we give the strongest known relativized evidence that $\mathsf{SZK}$ contains hard problems, by exhibiting an oracle relative to which $\mathsf{SZK}$ (indeed, even $\mathsf{NISZK}$) is not contained in the class ...
