Geometry‐derived statistical significance: A probabilistic framework for detecting true positive findings in MRI data
Sign Up to like & getrecommendations! Published in 2023 at "Brain and Behavior"
DOI: 10.1002/brb3.2865
Abstract: The false discovery rate (FDR) procedure does not incorporate the geometry of the random field and requires high statistical power at each voxel, a requirement not satisfied by the limited number of participants in imaging… read more here.

DOI: 10.1002/cncr.33369
Abstract: SELECTING PREDICTORS OF INTEREST BASED ON STATISTICAL SIGNIFICANCE Observational studies published in Cancer may seek to identify risk factors for an outcome of interest by using multivariable models or multiple univariable models if the sample… read more here.

DOI: 10.1002/jaba.938
Abstract: This article describes the use of statistical significance tests and distance-based effect sizes with behavioral data from single case experimental designs (SCEDs). Such data often are interpreted only with visual analysis. However, a growing movement… read more here.

DOI: 10.1007/s00259-019-04467-5
Abstract: More than 800 researchers, many of them prominent biostatisticians, called to “raise up against the p-value.” [1] This recent battle cry was just the climax of a growing insurrection, which prominently surfaced in 2018 when… read more here.

DOI: 10.1007/s10618-017-0521-2
Abstract: Statistical evaluation of biclustering solutions is essential to guarantee the absence of spurious relations and to validate the high number of scientific statements inferred from unsupervised data analysis without a proper statistical ground. Most biclustering… read more here.

DOI: 10.1016/j.jclinepi.2020.02.011
Abstract: OBJECTIVES The fragility of clinical trial findings has been previously defined as the number of changes in outcomes that are required to change their statistical significance. We show that reliance on statistical significance alone provides… read more here.

The statistical significance filter leads to overoptimistic expectations of replicability

DOI: 10.1016/j.jml.2018.07.004
Abstract: Abstract It is well-known in statistics (e.g., Gelman & Carlin, 2014) that treating a result as publishable just because the p-value is less than 0.05 leads to overoptimistic expectations of replicability. These effects get published,… read more here.
