Statistical power in network neuroscience

open access: yesTrends in Cognitive Sciences, 2023
Network neuroscience has emerged as a leading method to study brain connectivity. The success of these investigations is dependent not only on approaches to accurately map connectivity but also on the ability to detect real effects in the data - that is, statistical power.

The lack of statistical power of subgroup analyses in meta-analyses: a cautionary note. [PDF]

open access: yesEpidemiol Psychiatr Sci, 2021
One of the most used methods to examine sources of heterogeneity in meta-analyses is the so-called ‘subgroup analysis’. In a subgroup analysis, the included studies are divided into two or more subgroups, and it is tested whether the pooled effect sizes ...

Low statistical power in biomedical science: a review of three human research domains [PDF]

open access: yesRoyal Society Open Science, 2017
Studies with low statistical power increase the likelihood that a statistically significant finding represents a false positive result. We conducted a review of meta-analyses of studies investigating the association of biological, environmental or ...

Design sensitivity and statistical power in acceptability judgment experiments

open access: yesGlossa, 2017
Previous investigations into the validity of acceptability judgment data have focused almost exclusively on type I errors (or false positives) because of the consequences of such errors for syntactic theories (Sprouse & Almeida 2012; Sprouse et al ...

Admixed Populations Improve Power for Variant Discovery and Portability in Genome-Wide Association Studies

open access: yesFrontiers in Genetics, 2021
Genome-wide association studies (GWAS) are primarily conducted in single-ancestry settings. The low transferability of results has limited our understanding of human genetic architecture across a range of complex traits.

A Guide for Calculating Study-Level Statistical Power for Meta-Analyses

open access: yesAdvances in Methods and Practices in Psychological Science, 2023
Meta-analysis is a popular approach in the psychological sciences for synthesizing data across studies. However, the credibility of meta-analysis outcomes depends on the evidential value of studies included in the body of evidence used for data synthesis.
