A practical guide to calculating Cohen’s f2, a measure of local effect size, from PROC MIXED

open access: yesFrontiers in Psychology, 2012
Reporting effect sizes in scientific articles is increasingly widespread and encouraged by journals; however, choosing an effect size for analyses such as mixed-effects regression modeling and hierarchical linear modeling can be difficult.

Using Anchor-Based Methods to Determine the Smallest Effect Size of Interest

open access: yes, 2019
Effect sizes are an important outcome of quantitative research, but few guidelines exist that explain how researchers can determine which effect sizes are meaningful. Psychologists often want to study effects that are large enough to make a difference to

Finite-size effect in shot noise in hopping conduction

open access: yes, 2013
We study a current shot noise in a macroscopic insulator based on a two-dimensional electron system in GaAs in a variable range hopping (VRH) regime. At low temperature and in a sufficiently depleted sample a shot noise close to a full Poissonian value ...

Confidence Intervals for Standardized Effect Sizes: Theory, Application, and Implementation

open access: yesJournal of Statistical Software, 2007
The behavioral, educational, and social sciences are undergoing a paradigmatic shift in methodology, from disciplines that focus on the dichotomous outcome of null hypothesis significance tests to disciplines that report and interpret effect sizes and ...

Association Between Social Support and Health Outcomes: A Meta-analysis

open access: yesKaohsiung Journal of Medical Sciences, 2003
The purpose of this study was to examine the relationship between social support and health outcome variables, and the effect size of social support on health outcomes.

Estimation of complex effect-size distributions using summary-level statistics from genome-wide association studies across 32 complex traits

open access: yesNature Genetics, 2018
We developed a likelihood-based approach for analyzing summary-level statistics and external linkage disequilibrium information to estimate effect-size distributions of common variants, characterized by the proportion of underlying susceptibility SNPs ...

Fluctuation corrections on thermodynamic functions: Finite size effect

open access: yes, 2013
The explicit thermodynamic functions, in particular, the specific heat of a spin system interacting with a spin bath which exerts finite dissipation on the system are determined.

Adaptations on the Use of p-Values for Statistical Inference: An Interpretation of Messages from Recent Public Discussions

open access: yesStats, 2023
P-values have played a central role in the advancement of research in virtually all scientific fields; however, there has been significant controversy over their use. “The ASA president’s task force statement on statistical significance and replicability”

Finite size effect of harmonic measure estimation in a DLA model: Variable size of probe particles

open access: yes, 2008
A finite size effect in the probing of the harmonic measure in simulation of diffusion-limited aggregation (DLA) growth is investigated. We introduce a variable size of probe particles, to estimate harmonic measure and extract the fractal dimension of ...

MetaAnaly: The platform-independent computational tool for meta-analysis in the paradigm of new statistics [PDF]

open access: yesNetwork Biology
Meta-analysis is a statistical method used in systematic review to quantitatively integrate the results of multiple related studies to obtain a pooled result that can represent these studies. Meta-analysis overcomes the limitations of traditional reviews
